Seriously folks, this is called growing pains. Happens to all MMO's at launch. WoW was the exact same. I don't agree that it should happen (MMO's have been around for years, there's no reason anymore companies should have this "Oh TRIBBLE we have more then expected" thing anymore).
Anyway it's not that bad. I logged in, it said I was 330/330, then 313, then about 4min later I was in. The number didn't count down, just popped me right in out of the blue.
