Good MMORPG?

What are some good MMORPGs? I've seen a lot, and played a lot. Most of 'em I played sucked, so now I'm looking for something new.

What I've tried:
- Ragnarok Online
- Guild Wars
- City of Heroes
- Maplestory(WTF??<S>JFD!)
- Runescape(LOLWORSTRPGEVER)
- ???

So, yeah. Any suggestions?

pick a new genre
