Aion

I played a little bit of Aion. Only the first four levels, so I can by no means remark on the whole game. It plays very much like WoW or, more accurately I think, LOTRO. The interesting bit of its combat is the idea of 'chaining,' though I'm sure it's not new. One combat ability unlocks only after a first ability. With several options for each of those, you could build a reasonably flexible series of combat chains. Of course, you don't want too many...

The other thing that struck me is the way they treated wings. The fact that players get wings upon level 10 is a big selling point for their game, but I'm not sure why they waited until level ten. With wings integral to combat and crafting, why don't they start you out with them from the get-go? Or allow you to play them in the introductory sequence before depowering you, giving you a taste of what you're working for? I might try to get to level ten and try out the wings, but I think they messed a trick by not putting them in early.
