Some things i personally would like to see for the rp side of things are maybe some quieter activities to do in character, fishing, crafting, mining, things that let you have some down time away from combat. Maybe some player controlled cities or player run areas in general would be a nice thing. I don't know what the staff is like, but maybe running some in character events, like a few dungion rades for specific levels, things like that.
Something semi related that I personally would love to see in a game that I figured I would mention here is the capability to have a mage that can make spellbooks of rare or even one of a kind spells that can be sold, passed down, or put in a library for others to learn from. Not specifically just for a mage, but that's usually my favorite class.
