I personally prefer Hc over Core because i find it to be more realistic. I find Core game modes to be to childish. In core you can eat an entire clip from a LMG and live , but a knife to the ankle kills you ??? You have a permenant map up so you can see where everyone is who fires an unsilenced gun. If you get sniped you have a kill-cam that shows you where the person is that kills you. And if you do shoot someone but not kill them , they just have to go around a corner and their health regens. You have a permenant cross hair on your screen so it takes no skill for looking down the sights of a gun. Its like they made core so easy that a 5 y/o would have no problem finding someone to kill them. And before all the core players start blasting about camping. Core players camp just as much and when we do camp in HC , its because we dont have the luxuary of being able to eat a full clip from a gun and then have our health regen.
