Oh yeah. Soon Im gonna post a video where my entire body (except for the heal and barrel of the gun on my back) is through one of the "doors" on Epitath and I fire a rocket but it exploded as if I shot the door. That`s just a glitch or lag though.
Its not a balancing issue (although it works that way). It`s actually because grenades, bullets, etc. do not come off the hand or out of the barrel that you see. Its just animated that way so you see it like that. The bullet you get hit with actually comes from the enemy`s face (where their camera is). That`s why someone can shoot you even if you can only see their face.
