lol so true… 
However, you would also be surprise how “sometimes” people of the story/writer team actually create or use these to get not only the personal options of players but also a really good deep feedback into events in the past they might overlook that players still remember or even how players view these events (that they can’t get from reading a Lore written text)… that can easily be over look by the 10+ years of lore and story WoW has. 
/sighs
Someone never read “Blood of the Highborne” it seems. Let me “illustrate my point”:
From “Blood of the Highborne” part 6378 of 7511 (85%), Kindle version:
*Someone from the crowd shouted, “So we should leave! Get as far away from it as we can! There is nothing here for us anyway!”
“The Sunwell suffuses us no matter where in this world we may be. We cannot outrun it or outdistance it. Our reality is this: we must make our stand here, now, or risk losing everything.”
“We have already lost everything!” a young female countered.
"No! You have your lives. And while we have our lives, we have also this land. This is still our home. We can rebuild! But not with the Sunwell´s threat looming over us."*
From “Blood of the Highborne” part 6544 of 7511 (87%), Kindle version:
*“Today we fought and destroyed many of our own kind-malign creatures that had once been elves, elves I had known since childhood, elves I had loved and respected…”
Liadrin tightened her grip on Galell´s shoulder, then let go, turned, and walked away.
"The attack on our people and the destruction of the Sunwell mark a new and dark chapter for us all, but we shall adapt, and we shall prevail, and we shall rebuild!"
Lor´themar looked into the eyes of the survivors, and he beheld there growing traces of hopeful anticipation. Even Solanar raised his head and gazed wistfully.
"We must put this misery behind us. We must enter a new chapter! And so I say to you that, as of this day, we are no longer high elves! In honor of the blood that was shed throughout this kingdom, in honor of the sacrifices of our brothers and sisters, our parents, and our children, in honor of Anasterian… as of this day we will take the name of our royal lineage! As of this day, we are sin´dorei! We are blood elves!"
Kael´thas surveyed the audience and noted the restless upturned faces, mouths repèating the words.
“Sin´dorei…”
“Blood elves…”
“For Quel´Thalas!” the prince shouted
“For Quel´Thalas!”
The prince raised his arms, and the verdant orbs around him flared brightly.
“Hail to the sin´dorei!”.*
I hope both dialogues I quoted are clear enough to make my point. At the end of the day, the elves were submerged in a derrotist mentality -quite normal after the catastrophe they survived and the fresh traumatic events they probably were relieving in their minds-; but it was Kael´thas the one to give them their courage and more important, hope and faith, back to them.
Actually no, the sources haven´t. The very old and the very young still died, you know. This is still canon, and the proud fools of Quel´lithien are a perfect example. The “lul, high elves aren´t addicts!!” headcanon is just that: headcanon and BS. All the thalassians are still dirty arcane junkies.
Welcome to the “Blizz, WTF did you do to Kael´thas!!” argument made in TBC. THIS is the reason people says Blizz basically retconned the character and made a parody out of him in TBC.
Kael´thas is a loser only if you hold in high esteem the crappy writting made in TBC ands believe it was totes the coherent character development to be made. Or if you´re one of the Helfers prone to look a things only from a biased PoV.
Then he immediately proceeded to dedicate himself and his best forces on suicidal assignments from Garithos and would have accepted being executed if Vashj didn’t save him.
Upon seeing Illidan, he immediately starts calling him lord and master. He wasn’t ruined by the TBC, he was made into a lackey from his debut.
Medivh was a traitor too. Hence why he or his ghost or his echo is currently on a redemption tour. It seems to me that Kael’thas could do something similar while Lor’themar remains the Blood Elf leader.
Or Kael’thas could remain in Revendreth.
He’s a perennial joke. A loser. He’s been both since WC3. He’s never stopped being one ever since. He continues to be one in Shadowlands. I don’t see the character’s appeal as a mainstay.
Sure, Blizzard has written him terribly in WoW. But he is a Blood Elf character with history in the franchise who has a fan base. Surely, it’s possible for Blizzard to write him better and rehabilitate the character. And isn’t that better than trying to build new Horde characters from the ground up?
I don’t like Kael at all, I respect Lor’themar though. They could have messed his story up and yet that is all I’ll remember him for, he’s no rock for Quel’thalas the way Lor’themar has been.
I really don’t care if Kael’s story was done dirty, so was my favorite character Sylvanas Windrunner, or Garrosh. Etc.
Calling Lor’themar a rock fits perfectly…but probably not in the way you intended it.
More kael’thas content with the venthyr covenant campaign
Wow I’m so Hype thanx! I have mix feelings of nostalgia and excitement! 
Nostalgia for the return of our Old Blood King but excitement because this Keal’thas feels new… if that makes sense.
I really like and am very intrigue the direction this new character development is going! Can’t wait for SL! 
What redemption? He never stopped his antics and was forced to stop by dying twice. When he talks about redemption for Silvermoon, he basically means “Kael’thas” instead of Silvermoon. The only problem he has with his people needing justice is because he wants to be the leader of an army or just still upset about how things turned out for his followers and mean them. He basically made sketchy deals with Illidan over the promise of his people being able to self-sustain and when he ended up handing the blood elves to Illidan. His guys and most of the blood elves left his side, and some stayed and carried out all that bad stuff he was saying he didn’t know was going to happen when he allied with Illidan, yet he turns his back on most of his people and kept causing problems like his job to summon KJ through the Sunwell. Yeah, he was involved in that. He went from an easily offended leader to get a taste of power and betrayed everyone. If he were trying to redeem for the right reasons, he would not have tried to level the Sunwell after what happened, and just each thing went on.
He will turn Silvermoon into whatever the people with the biggest power juicer want to self-corrupt themselves. His character lost its potential before WoW started.
Even if he suddenly got self-control and has the best intentions, there is not one blood elf in leadership roles that would let him run his own pawnshop, let alone be a part of leading the blood elves. It isn’t a problem if he isn’t completely alive; unlike the Alliance, Horde doesn’t stop rightful leaders from their role because they are technically undead. If Lor’themar died and were a ghost, he would be able to resume his position.
Kael thas did to his people is something he just can’t be redeemed for and accepted as someone who can control anything blood elf related and isn’t going to be told anything
that is going on like fights, plans, etc. His best hope is to be exiled from Silvermoon still and be able to interact with Quel’thalas or Quel’danas again in his life. He did too much damage, and there isn’t really anything he can do to prove that he won’t randomly betray everyone again.
I totally like Kael’thas, I think he’s cool, yet that’s not realistic. He’s just gonna be exiled ghost Kael thas at best.
All I really want, is for Kael’thas to send the hero back to Lor’themar with a message saying that he wishes for Lor’themar, to begin the Theron dynasty.
Kael’thas was implied, even before he went nuts, that he wanted the monarchy to end with his father.
Although a lot of that was grief talking, he was relatively young, probably not quite a thousand years old, and definitely expected to remain a prince for a long time.
My main problem with BC Kael, honestly, is that he started a long line of people who were presented as basically unreasonable for feeling things about their people getting genocided. So while Erevien’s post is absurd and he doesn’t really get the character because he’s too obsessed with the stupid team jerseys, I at least get the people who see how he got shafted in BC.
I could feel the wheels turning towards Tyrande’s own Tempest Keep as I was starting the Darkshore intro scenario.
The thing is Erevien doesn’t understand in what way he got shafted.
Unless if you do something like what Illidan did Body, Soul, and everything. I mean his Body is probably already rotten now after all of that Fel Corruption that poisoned his body Kael’thas that is.
melisandre is the kael of the nightborne and both needa come back
Begone foul necromancer! Leave the dead be! They have suffered enough already from shadowlands!
Go back to the abyss!
Blood Elves should elect a new King. Lor’themar needs to step down and live with her wife on her estate
Or if they’re gonna revive their Sinfall-bound Prince, better rename the country to Sin’thalas
They should elect a new king, and you want the most competent of choices to step down? Nah, if anything, Lor’themar should begin the Theron dynasty.
The only scenarios I see SL Keal’thas return or allow to return (IMO) in anyway that would “Kind of” make sense would be:
Let’s not bring the villain who tried selling his people out to the Legion back to rule them, thanks.
