Horde having Blood Elves and Nightborne means NOTHING - for their magical strength, because the Alliance have Jaina to flex on all of them and make them look pathetic or scrabble to match her power.
Without Jaina? That’s fine, the combined “might” of the Nightborne and Blood elves will be equally matched by the humans of the Kirin Tor and “Alliance-Only” High Elves, maybe a few Nightelves with their new Highborne allies made in Cata too. …
So ultimately …
Alliance win every cosmic, magical and aesthetic in the game.
If the factions are to unite in some grand evolution both in lore and gameplay, naturally the Horde will be dissolved – and their races will join the Alliance who clearly, easily and obviously triumph over the Horde at this point in time.
Odd questions for both sides in this thread:
Horde — Which magical field would you like to see hold more relevance & significance over most others?
Alliance — Which race would you like to see get more relevance & significance other than elves or humans?
And it’s displayed like a sloppy crumbling noodle compared to the juggernaut of the Alliance’s magic.
If Blizzard ever utilised Nightborne time magic, I’m sure they’d write it as having the Alliance just finding a simple easy way to dispel it – with little to no consequence or hinderance of their path forward.
Elisande kept entire armies frozen in time until we murdered the monster that fueled it. I’m sure the Belves would find a grand powersource to fuel such a spell and aid the Nighborne. Especially since their leaders are you know… married.
It would likely still be not a fair match in magics, but it’s at least a very annoying hurdle.
Although, if they played it right and used that trap to just contain Jaina, the fight could be more even. XD
Blood elves should be the strongest mages on Azeroth.
Problem is that Blizzard likes to make humans be the best in almost everything. And the few things humans aren’t the best in night elves are. Shamans are the sole exception, which might explain why there’s been like no shaman lore since Cata.
