Seeking a good MMORPG game.?

I have grown tired of playing my games, and are seeking a new one. It can be p2p but I don't wanna have to pay an outrages amount. I don't want to have to download it, but I can if needed. I have played Runescape and Guild Wars I perfer to have skills to train, storyline don't really matter, tho it will help. I also perfer mid-evil type games, not a fan of futuristic games.
