It almost seems like armor breaks in 2-3 hits. I tested a new bronze armor set on a zombie and took 1 heart the first hit, 2 hearts the second hit, 2 1/2 the third, and 3 hearts the fourth hit. The armor durability doesn't move at all for this though. This was on difficulty 3 and I would like to see some fix for it since armor is a huge part of survival play.
