1. Most of the people typing in caps lock are idiots
2. "casual" gamers got the better end of the still with skill based matchmaking. They didn't get shat on by 2-3 kd players like me all the time. I have to constantly put up with 3-5 KD players (I know there aren't that many great cod players in my area, so something else is involved.)
3. Pre patch dead mans nuke didn't support casual players?
