Kayotix isnt outside the US, so I'm not sure what that has to do with warzone.
Game mode just needs some ballance. When it swings one way it usually swings hard and it's hard to come back. Most fun I've had in War zone is when it's back and forth.
And we usually have a group of 4 or 5 when we play also. Would love to see what a full 12 man squad would do lol
