Does anyone know of a mmo that has good combat.  It would also would be nice to include something with a good amount of quests, and a decent community.

"Good" is subject to opinion. What kind of combat do you prefer? FPS, RPG, action, a hybrid? Do you like PvE or PvP? Do you like large battles or small ones? Do you mind hitting the same keys over and over or do you want something more engaging?

Well, my opinion of "good" combat would be Guild Wars.  Its a game that requires a lot of strategy when in combat, reason being is because you can only have 8 skills on your skill bar at a time, so you need to come up with a strategy that works for you before heading out to do a quest/mission.  The game is filled with sub quest and main story missions so you wont have trouble finding those.  Also, for the most part the community is very friendly and helpfull. 

DDO have the best twitch combat in my opinion. Its very fast compared to all other MMOs Ive tried and takes alot of skill.

Ye we're gonna need a little more detail on what you like because right now i can think of alot of games thain in MY opinion have a good combat system.

By the way, Planetside. Quite simply the best MMO I have ever played.
