Dont expect anything lol.
I'd want skill tree or such, where you can spec any job for any role.
Wish they would stop removing skills, to make room for new ones, to prevents skill bloat, and split skills beetween roles instead.
Also different weapon stance/combat styles, so you could use lets say melee aoe stance, or single Target dps, or defensive stance - each stance having its own skills.
Unlocking classes, so you could have Lancer Dark Knight, or whatever.
