na, I like the combat system in how it is, I know there is some waiting involved but at the same time it makes you think about what you do and if you should perform your action now and wait about 2.5 secs for the next one but by then the other mob is chasing after the healer because you used your Aggro combo on a mob that you already have aggro on.

Also lag, I remember watching a video about action MMO's and it said one it's cons is how lag can be very damaging to you. We can get away with a little lag in this but action mmo's require near enough a perfect internet connection.

But that's not to say I don't like actip RPG/mmo, one of my fav ones is on FF7 CC. I think they did a great job on that action wise.
