I was also in that run. It wasn't even the worst experience. Yesterday with the same group we managed to get all 6 parties in an instance and progged the first boss for the first time and got it to 10% enrage. We were all prepped and ready to go and get the kill but had to try to do the instance roullette all over again because the instance timer ran out. After 2 hours of trying to re-organize people just gave up and we were stuck with that 10% enrage.
