Had fun but didn't stay logged on for all that long. In my humble opinion there needs to be a little more to do once you log in. You can't kill enough mobs to reliably quest. There's no PVP to be had immediately upon logging in. Again I know it's just a stress test but if you want to really peak the logged in population then you should consider what's going to keep people playing once they're logged on. I think I saw 20-30 people sitting on top of Sarkoth waiting for him to spawn.
