r.i.p. alleria. 1997-2017. blizzard ruined alleria forever. blizz assassinated alleria's character and appearance.
i will never forgive you for this blizzard.
Moira from Overwatch.
She is unlikely, in my opinion, because Zenyatta absolutely should be in the game before her. But she is probably my favourite hero in Overwatch, and I would like to bring her into HotS, as well.
Arcturus Mengsk was a good villain. I don't know how he'd play, but Gazlowe and Cain show the HotS team can be imaginative with their hero design.
A less-known Forsaken character would be nice, like Lydon, Faranell or Belmont.
Now you see it. Now you don't.
But was where Dalaran?
Lei Shen, The thunder King (though I see a lot of people want him so maybe just maybe he will be added)
Xavius , The first Satyr - the dungeon model with him being all about curses and the Nightmare
Grand Apothecary Putress - Make his kit revolve around the plague, alchemy, aoe and area denial.
Dargrul or Navarogg - the Drogbar creatures added in Legion, something about pikes and rock fists shooting up from the ground just seems cool.
WoD Arakkoa - all about blinds and mobility
Zul (unlikely just because we already have two characters with that name) - show the united Troll Tribes, kind of like Kharazim or Varian: Faraki Allegiance for ambush and roots, Drakkari Allegiance for slows and stuns, Gurubashi Allegiance for brute force and sustain.
i would like to see a shadowpriest char, 2 dots and mindblast, passive would be voidform, granting %dmg or haste, and ulti shoould be Void torrent or void bolt, void torrent for the burst and bolt for the sustained dmg
The longer this shitshow is going, I am starting to assume characters like Mephisto, Kil'jaeden or Imperius are rather unlikely.
