quick question what u mean by DC?
Basically, Bryan and I were in keeps 1, we were fighting a pack that had arcane (I don't remember the exact affixes off the top of my head). I was on one side of the pack, Bryan was in the thick of it, and they dropped some arcane too close to me, they hadn't popped the arms of the beam yet but there were 3 or so of them, so I started moving toward the pack and Bryan w/ the intent of teleporting to the other side to get away from the beams dropped so i could continue DPSing.
When I hit teleport ... my character did not teleport, and I was running around unable to use any skills - which is the basic indication you're lagging *huge* and not talking to the server. The game stayed like this for a few seconds, I was spamming DS in the hope that the spike would end, catch up, pop the ds and that *might* save me - Then the game kicked me out to the login screen with an error. At which point I tried to log back in, and couldn't. Then I checked my profile and saw the (dead).
I suppose it's technically possible that I died while still lagging and that caused the error that booted me out.
