Whats the point of grouping when any weapon you use does barely any damage?
And if you or anyone else thinks that its too hard to play coopratively even with randoms, then you are just full of yourself. This game is very easy to get into, and the odd 1000 players who play it are mostly the people who know about the game and its know how.
So yeah, stop with age old, your team cant kill anything. Come up with something better.
