A little TL;DR so I just skimmed to see what characters you’re getting rid of (I could only see Shaw - which lowkey feels burying your gays-y but whatever - and Thrall? But again, I skimmed pretty fast) and I sorta have a problem with that because…
…to actually do that, Blizzard needs to introduce new characters that’d serve as replacements. I wouldn’t say that’s necessarily a status quo thing (f.e. writing out Tyrande and having some new character become the new Tyrande serves very little purpose), but the way it is now Blizzard writes out characters while having no new characters to stand in. And this creates problems where… well, a lot of a race’s story is told through their main characters. When they die, there’s nobody to tell the story for that race any more.
Some races don’t have that problem, Humans lost Varian and had Anduin to replace him, then lost Anduin (temporarily, at least) and had Turalyon replace him. Even that replacement has been clunky, actually - have there been stories about how Turalyon was received or how (in)competent he’s been at leading them? I’m sure the Nobles would not like Alleria being present as well because of y’know, Void.
Orcs have had Thrall be replaced by Garrosh, and then Vol’jin replace Garrosh, and then… oh wait, it’s Sylvanas now. Aaaand she’s gone. Okay, I guess Orcs haven’t had that many as well. With Saurfang dead, who even is the notable Orc Character now, Eitrigg?
I think before Blizzard starts making away with old established characters, they need to write in new characters at least one expansion prior, so that you’d have the audience get to know the characters first. It’s why I was so hopeful after reading Elegy at the beginning, because 'oh wow, a new Night Elf character? I find her interesting, too?? Could it be, she’s – dead, apparently. ’
I’m sure the Draenei players would’ve similarly been excited over Yrel only for her to be struck with the expansion curse. Blizzard really did build up an entirely new character that the players accompany from the beginnings to basically leadership and just drop her lmao. And I guess Horde players have it even worse, because there’s a mandatory change in Warchiefs at least every two expansions, but again - no real new characters to replace the old. There’s a council now at least (from what I remember?), so maybe the curse of being a Warchief finally ends lmao.
