Simply because everyone wants to be a damn sniper. I do not know what is worse lately in Modern Warfare 2, at least on Xbox 360, snipers or grenade launchers aka “noob tubes” because both are out of control.
I never understood with a game so unbalanced and with so many weapons, perks, killstreaks and the dumbest of them all, deathstreaks, would even need grenade launchers. I will not even get started on pain killer, we all hate it and those who suck, which is majority of you out there, most likely use it. If you were good player, you would just put on copycat and just never even use it, or use it, at least it is not as bad as the rest.
