That's a no no in raids. You don't yell at each other an accuse. You admit your mistakes and real friends help you fix them and give suggestions. Maybe even take the spot you're in. But yiu don't yell.
Well, it wasn't really that much raging. Nobody actually ragequit (anybody that did leave during the attempts legitimately had something to do). Things just got a bit tense after one too many minor mistakes on the Warpriest fight. There was a bit of anger but generally we were calm and chill about it. All of us (along with a couple other cool guys that were helping us out) were pretty friendly and coordinated, and one of them actually said we were a pretty decent team that made up for each others' weaknesses (like a player screwing up platforming or someone dying at a horrible time during a fight).
