As far as I know, Balmung and Gilgamesh are the only servers with actual roleplay-centric communities. There absolutely are roleplayers (or at least people open to doing so) scattered about other servers, but short of getting your friends into it, it's not likely you'll find much luck. Who knows, though? You could ask around, get others interested, and maybe make a linkshell for it. You don't need a huge community to have fun with RP so long as you find a nice group of people.
Hyperion does have at least one RP-friendly FC in Tonberry Cutlery Inc, but I'm not sure how active they are. Either way it's a good place to start!
