Wiping on Gharj and then sitting outside the instance waiting for one more death to randomly come for everyone before re-entering is always fun.
Just respawning after a wipe in general sucks. It's gotten to the point that every time we do, we hold our breath that we can re-enter the instance without 1) Not having to reset and therefore re-clear all the trash (Especially leading up to Gharj... UGH!) or 2) The instance bugging out completely like it did for us last night on the Ancient Pylons in Nightmare mode. We couldn't get it to reset at all and had to call it.
