Yes, this is the serious problem... You know, great MP game is created by good fair players, not the game only itself!
I found many morons, who theft my armor, which i bought in Warfare mod + they were unable to consume the fact, they had to travel across the map, so they just enjoyed killing other team players on respawn. But sometimes, SOMETIMES, i found really great server with people with great sence of team playing and it looks incredible.. This experience reminds me, how much this game worth:)
