MOB SWARMING is Insane!!!

Can we please fix the mob swarming still having isses where bosses dont kill you but a tiny bug will ... how hard can this be. This issue isnt in POE1 why is it so hard to get this balance right. Plus trials are still impossible and the penalties to resists in the different acts is crazy...end game im - % on 3 resists and i have heaps on my gear. People are leaving in droves and going back to poe1.
