EDIT: After turning my ability queue time to zero, I've been having a seemingly much more responsive time in combat. I have to say I haven't noticed any major problems since turning queuing off. I would highly recommend that anybody having trouble with responsiveness try disabling ability queuing as a first troubleshooting step to see if it helps. Granted, for high-end cut-throat players a well tuned ability queue time may be important in order to squeeze out those last percentage points of efficacy, so this is not an ideal solution even if it does solve the problem for some people. Original post (see edit above): Delay in ability response is critically important. I have opted not to continue playing an MMO before almost entirely for this reason alone (Vanguard was the game - combat was quite clunky and did not flow). I've noticed unacceptable delays when I use abilities in this game, but it is much better than it was in Vanguard. I am willing to stick with this game for one month after my free period to see if the bumps are smoothed out. I expect smooth responsive combat during which I receive near-instant feedback when I use an ability. I hate when there's a split second delay after I use an ability but before I receive any feedback, during which I second-guess whether I successfully used the ability and must decide whether to reuse the ability or continue waiting for the game to let me know it's doing what I tried to tell it to do. Despite the rough spots, I have been largely enjoying this game so far.

For me, the map becoming transparent while my character is moving so the world and map are visible at the same time made me happy. I thought it was a good idea and I've never seen it before in an MMO. So what little (or big) things caught your eye?
