Was my behaviour on War inexcusable? The other day I reached breaking point in War with teammates not playing the objective and hanging back sniping. It was on Neptune twice, first on the beach and then in another game when trying to destroy the artillery. 
By the time it got down to around the 90 second mark and it was clear we were not going to complete our goal I would then just start putting down smoke right in front of the player who had hung back and incompetently sniped for the whole game. If I got killed I'd go right back and smoke them again.
I realise this was poor form by me but I'd had enough of it.
