The final boss fight is absurd. Your typical PUG group (at least on The Bastion) has no chance of ever completing it. If everyone was as good as I am it would be a piece of cake, but unfortunately that's never the case. I'd recommend halving the number of adds that spawn in each wave, reducing their damage by 10%, and eliminating the boss' random AOE's during the add spawns. It's just too much for the average player in The Bastion's HM queue to deal with. I've done it over a dozen times and the players, especially ones new to the fight, always get overwhelmed by everything going on and die or remain oblivious to the add spawns, which causes me as the healer to instantly die. It turns into a wipefest which always falls apart.
