Try RYL. It has an awesome combat system. SO good that just the combat alone, although brainless hack and slash, is still insanely fun. The combat is real time, and somehow is still fair in PvP fights. Only problem is the massive kill stealing. Noobs take advanatage of the combat by delivering the final blow, or just beating on monsters already being fought by other players. This lets them get massive SP for no work and the original fighter gets half of what he should earn. Not a great community either, but if PS adopted this real time system, it would truely be a force to be reckoned with.
