Yep. It does... Sometimes you can go against some really powerful masters of the game, sometimes you get the team of noobs and sometime your enemy is the team of noobs...
Oh... There are also games where you lag like hell and noobs in enemy team win because of that... I shoot enemy in the head, he should instantly die but he turns around, shoots me in the head, kills me and only then he finally dies...
And sometimes lags are so severe, you get teleported all around the place and even 4 shots in the head won't kill the enemy...
