LOL at first Nade kill - the dude threw it and you ran right over it. U wait till it blows you get a double kill when turning the corner......
Can't watch all 20 minutes.......There is no such thing as camp'n on defense in rush, the goal is to protect the charges at all costs (I personally never stay in the same spot for more then a second or so...but when i see a teammate in a "camp'd" position - I know if he goes down the charge is at risk and I fall back. )
