I’d ask for data to back up the ‘most’ part, but that’d be mighty boring. Let’s spice this up instead: ha, are you even sure those players (two separate links, although to the same sample) you refer to are old enough to have ever seen WC3, let alone read its manual with the lore? I could expresss my disapproval at how substantial parts of it have been ‘retconned’, but I’m not sure if there’d be many here who’d appreciate. 'I dunno and don’t care 'bout nuthing, gimme two packs and a deck code! 
’
Me neither, by the way. I do remember WC3 and its manual, though. Not sure if it’d make you so willing to side with Sargeras.
Yes, you could, and it’s your choice to do so or not, but it’s occasionally not that bad, for example, to get some background to the characters and stories that you play with in this game, too, if you ask me.
Yeah, especially Shadowlands.
Take a look at this (could find the video on the official channel, but what of it):
‘A fitting end’ 
, as per Yogg-Saron’s quote from Mercs (lemme add a sarcasm marker for those who couldn’t detect it via text), but that’s another story.
If you’re really interested, I think I’ve expressed my positions about all of this — the Titans, the vote… Arthas’s story, even (by the way, while digging this up I found a reminder that you’re his fan) — quite openly in my posts, do I really have to repeat any of it?
I’d nominate this for the ‘Best and Most Solicited Advice from Sheep’, but can’t be bothered.
‘We’re gonna be rich!’ — except with six measly packs, yay!
