Looking for a new MMORPG to play~

Hey everyone, so I just recently quit FFXI due to the game being corrupted by the past few updates which added Abyssea.
Anyways, I had been playing FFXI for about 7 years and I'm now looking for another MMORPG to play.
It doesn't HAVE to be F2P, just looking for another game that has some pretty serious gameplay (ruling out games such as MapleStory and FlyFF <_<), and has a pretty integrated player-base.

Look at some of these threads first, thanks :).
