Physics

I am aware of the rubbish spouted about netcode, desync etc but there is something very wrong with the physics in the game.

Today i was about 2o m behind a squad mate as he entered a building and was killed next  second i was dead by guy who shot through his body into me killing me in 2 shots, i had full health as well.

Weapon ranges are awful how does an SMG out range an AR.  Shotguns with 80m range wtf.
