Nowadays you don't even need to do the imp punch on typhon thing. They nerfed the heck out of that fight and as long as you stand in the middle of the platform when he snorts, no one should get knocked off. Even with 8 BLU's, if you're wiping in that fight it is because you are completely disregarding the mechanics of the fight. Stand in the middle when he does the big charge up snort, rotate with ultros when he does the rotating snort, and stay in the center and keep moving forward when he does the repeated snort. Nobody should be wasting time attacking Typhon except the person tanking him, since he will give his HP to Ultros throughout the fight and doesn't really need to be dps'd down at all.
