On the topic of the AR people are suspecting is added, I think it’s possible it’ll be one of these:
-Darkfallen
-Sethrak
-Tuskarr
-Gnolls.
Lightforged undead have come up, but I have major doubts. Blizzard will likely want to add things that will get people to join again, and there’s understandably been a negative reaction to the idea. Alliance already have human models, and many Horde I’ve seen want nothing to do with the idea of LFU. Just from my observation.
Covenant races could be a thing, but it’s doubtful given people’s focus might want to be on Azeroth. Who knows. I’m not interested in souls that have gone through the afterlife being playable myself, and I know people have pointed out they don’t want to be reminded of SLs. There’s more of a following for them than LFU. I myself am not interested, unless it’s Stoneborn. Not venthyr.
Tuskarr I’ve seen asked for but much, much less. I suspect, though, the remodels might have a different tone. Still, I don’t know who would be pushed to preorder because of Tuskarr. Same with Gnolls, though I personally favor and would play Gnolls, especially after those cool remodels.
Then, there’s Sethrak. I think they’re the highest contender, though I’ve seen a ton of people suggest Darkfallen too. (Why not both? ) But yes, Sethrak have been asked for a lot, they are a cool reptile race, and they’d have multiple classes–which these dragon people will not have. This also applies to Saurok. Those like myself who want a playable reptile race on multiple classes would love both of those.
Darkfallen, finally, yeah–I’ve seen people suggest Night Elves for the Alliance, and Blood Elves for the Horde. Elves are popular, there probably would be a lot preordering for it, but I can’t speak for people. I know I want them. However, the problem is people are indeed sick of elves, which might be a block. Honestly? Who knows.
All of that said, Darkfallen customization would also be great for Blood elves, yes. I know people are questioning whether or not San’layn people would be okay with it, and I would. I just hope it’s more than red eyes & undead skin, is all. I’d love some lore, like a Night-Warrior-like questline, but as people have pointed out, it’s not technically necessary (even if I really want it )
I’d also hope DK would have access to said customizations. Different eye colors for DK, for example, would be a start.
