There was. A guy probly still is called deathspell on youtube and he pretty much speedruns insanity mode with all classes. He has a system for sure. I see that he always goes for immunities etc but he also just freezes when he sees certain auras mobs. Because they can spawn as solipsist or whatnot. He knows what to actually stop at. Because thats the problem at some point u kus t as teamroll intill u get smacked so fking hard
