Sure and if you have skills, big bollocks and an SMG you will make a lot of people that blame their oppenents gun for their lacking rage quit. Of course you can use any other gun and do the same but why not be cliche so that they'll make another SMGs make me cry thread.
This is just my opinion, but, if you cant change your style of play to suit the enemy players you are up against then you will be complaining alot. As I stated before, all players will play different and change strategies every few games. Adapt or else be complaining
