I would really want blizzard to add idle animations for each class like a pose/emote, for example:
Mages would maybe have a pose that would allow them to like hold arcane mage in their hand (we’ve seen this in game for quite some time now)
Paladins maybe same thing or holding their weapon infused with holy light
Etc.
This is something i think would be cool for everyone and especially role-players. There are a lot of already existing poses they could use so it cant be that hard
