I find it bullshit that the Countess and Mephisto on the lowest difficulty can 1 shot you even when you come back as a much higher level character.
I came back to the first act on 8 Player as a level 47 Paladin, did the first attack that killed ALL enemies in the room.....yet the Countess did 1 retaliatory attack and it killed me instantly. I had close to 2k hp. In my opinion, that is WAY too Overpowered and should be nerfed Immediately.
Same with Mephisto on the lowest difficulty. I was battling that PoS with absolutely NO problem.....then it happened, he cheated and 1 shot me. Wtf is up with this bogus mod?
