I played the final closed beta this weekend. The graphics were excelent and it ran smoothly. Flying/gliding is a ton of fun; it completely changes the experience of "exploring" areas that the devs didn't indend for you to reach (and there are very few areas that are unfinished and strange). You'll need to plan on a bit of grinding/not avoiding mobs on your way to complete quests, but you'll level up doing the quests pretty easily and I found most of the quests enjoyable. Also, there is a built in finder function that puts an X on your map where mobs/things are if you look them up, which is really helpful. I really enjoied customizing my character; I spent an hour messing arround and came up with something I really like.

There was some disapointment. You cannot invert your mouse look; this left me feeling sick to my stomach (motion sickness, I guess?) for the first few hours as I adjusted to up being down and vice versa. The UI is not fully customizable, though it feels pretty complete; my biggest annoyance is that I could not move the target unit frame down close to my action buttons.

All-in-all, I can't wait for the game to release.
