There is probably some heavy math issue with how armor/damage/resistances are calculated

i have all resistances capped, some more than 70%, 22k armor and 70k hp and i have an hard time on pit 80. I have noticed that even on Nightmare Dungeon 100 many times my hp got halved by a single shot.

It is very confusing what is going on, we dont have any debuff or dot indicators in the game interface. We dont have any damage log. I really can not understand how to fix my stats and gear rather than just stack stats on top of each other to the best i can.

I mean… surely there must be something weird going on.
