1.) Guilds.
2.) Player shops/Auction houses
3.) Camping system. There's campfires sure.. but how about making a tent with leather or something? Would be fun for roleplaying aspects. 
(Make it off limits in cities though for obvious reasons lol)
4.) Mounts. (not for combat) Even if they are just for movement increase. (The ranger buff can still apply though..)
5.) A Vanity inventory tab/bag. A tab in the inventory ONLY for Vanity items. The more added to the game.. the more inventory space they'll take up. Maybe even a bag just for Vanity items would be nice.
6.) More Vanity variety. The 2 V's lol
