One thing that does not make sense tho is sometimes you dont even fight or use your weapon once, or dont get hit once and all your equipement break.
There should be some sort of system implanted that add % that an item break if you use it or if you get hit in a certain location.
Exemple: If you fought during a round but never got hit in the head you should not have to repair your helmet. It should be affected only by where you got hit during that round.
