The last boss seems stupid hard, at least for the pugs so far. Even with a group of all 40+ it seems like its just not going to happen.

all the good players see running crush the keeper so its all pre 50s and leachers...

since the only reason to beat part 1 is to get to part 2, what's the best way to go about this? 4 times I've ben in a game where everyone left on the last boss becuse we kept wiping. What's the trick?
