I just watched a video on ESO Personalities and I was thinking it would be cool if WoW had something like this.
Being able to choose “animation sets” that might affect how you walk, run, sit, attack, etc. would be pretty neat (I’m still jealous Demon Hunters get their own stance like Monk BUT they have the benefit of being able to run with the weapons still facing outwards instead of just doing the normal “jog”.
I also think emotes need to be greatly expanded, choosing your animations would be cool - and what I’d love even more is to be able to individually choose styles for each emote.
