I've been in closed beta for quite a while, actually I think I got my account in one of the very first waves. And still I never made it past level 10 on any character, somehow it's one of the most boring MMOs I've ever played. Which is somewhat odd; the game is pretty well-made but still feels like Blizzard re-released WoW as some kind of cash-grab HD edition.
One of the most concerning things though is the funky performance, it's just all over the place. I'm still using my rig from 2 years ago or something, (OC'd I5 2500k, Radeon 6950 2gb, 16gb Ram) and it's fairly bad. Standing around the newbie zone my fps goes from 15-60 for no apparent reason and disabling certain options (like shadows) just does nothing, it stays the same.
I'd say right now it's even worse than it was at the beginning, which is usually not a good sign. A game which looks like a somewhat flashier version of WoW, yet is running worse than GW2 should not be released in 3 months.
