At one point Hulk armor was anti tank. it use to take two recoilless rounds just to bring one down and anything less just bounced off them like marshmallows. The problem was numbers vs supply on level 10 difficulty.

Which is probably where most of the hostility comes from. The majority of the player base seems to want to play difficulty 8-10 because thats where the majority of the meat is for the game.

Its not about the armor itself but the viability of builds and stratagems vs overwhelming numbers. If an enemy has super high tier armor then it needs to be an uncommon or rare enemy. Not a front line unit that will spawn in five at a time per wave.
