Does anyone else hate the halo 4 hitscan and aim assist combo?

I'm not even saying when it happens to me but also when it works out in my favor. I habw gotten thousands of bogus kills because of this system. Even after the kill i say yeah that wasnt a kill nor was it anywhere in the vicinity of a headshot. I couldn't tell you how many times my entire head will be behind a wall as I'm sprinting only to die while I'm behind a wall. Because of a) hitscan system and b) aim assist. I completely understand why halo 4 needed to be hitscan it helps with lag and negates the random missing of shots in halo 3. Trust me I understand that but it is very aggravating when your on a dead sprint and some guys reticle is on the back portion of your head and those shots are registering because his reticle is red when in reality he would be missing you by a couple feet. Now I'm not attacking hitscan I'm attacking the combination of hitscan and the absurd amount of aim assist halo 4 has. With the sniper anything from the sternum up including the arms is somehow a headshot. And don't even argue I have numerous clips in my theatre mode displaying this. And with the dmr your good for the headshot if you hit anywhere from the waist up. Sorry for the rant.
