I don't know if this annoys anyone else, but that second hit zombies do after a lunge is annoying. After a zombie leaps onto you, you get hit once then a second time, or is that only to shields.
This breaks shields faster. Especially when you're in a zombie mob.
One hit should be good enough if any of you agree.
From what I've heard, this is a Bug.
But if they were to remove it, it would make Zombies stupid easy again.
