Annoying...

I am liking halo 4 but there are a couple things that are annoying the crap out of me

Player collision is probably the most annoying to me. It’s a tad annoying how much you get moved around when you bump into someone or run into someone. My friend accidently sent me through a man cannon when i was sniping.

Second thing is the Auto-Aim Assist Lag compensation or what ever you want to call it. So many times I have another enemy run in front of the guy i am shooting with a machine gun or saw and instead of staying on the target i am shooting at, it starts to follow the guy running. That’s annoying and unacceptable. Why would anyone switch to another guy before the other was dead?
