I may pull an odd duck now, but while I have been preaching for an RP server for a long while, I'm starting bit by bit to see that at the very end, a server of -only- roleplayers would struggle to keep going. Roleplaying is an activity that takes high amounts of time and usually gives nothing back in terms of progress of the server's economy or status within the game's advancement overall (meaning, endgame content). A server without non-RPers would probably end up being with an inflated economy, with only few people farming and providing the market with items and materials (because most of people would be busy RPing, and RP takes time), and with very hard times in finding help for difficult content (because most of people would be busy RPing, and RP takes time). Duty Finder can only do so much to help that, and everybody knows the bad reputation DF pugs have in endgame content.

So, while I am mainly a roleplayer and have a sour eye for those who grief RPers and what they do, I don't think I could have a stable server's economy and community without non-roleplayers. I think Balmung is as close as how an official RP server should be in order to be functional.
