I've now got four characters... urgh, there needs to be an altoholics anonymous meeting or something. ._. Anyway; yes alts can be a chore on this game, but sometimes I just want to play a different character. I love making up characters in general (wouldn't mind being an author), designing them, creating their personality.... so when I play a game that lets you create your own playable character, I always have a lot of ideas... and usually end up trying to make a bunch of different ones. Yeah its probably an addiction.

Account-wide needs to be a thing for mounts, minions and barding. Maybe somehow glamours too (a system similar to WoW's new transmog system would be awesome). ESO also has account-wide mounts, pets and costumes. Can't speak for any other MMOs though as I only play those.
