I played POF maps with my thief and it was a piece of cake. I have constant healing with Signet of Malice, heals on critical hits and vampire rune-things on my armor. My lvl 80 warrior however dies withuout end. I can't complete any hero challenge solo, mobs on the map are always challenging. All my armor and weapons are orange, Berserker armor, trinkets are focused on vitality and healing. My armor has this vampire upgrades too and i use greatsword. I mean from a logical standpoint, the warrior should be more resilient than a thief but it's not somehow?
build: (Only berserker fully unlocked but was too squishy)
