Commando and Painkiller. Tone down noob tubes/OMA (even though I do it sometimes). Also nerf the dreaded MLC combination and fix the spawns a little bit and this game would actually be pretty damn good.

Yeah MLC is what pisses me off the most in this game. And I hate when people say shotguns work against them. I shot a SPAS right at the MLC'ers chest but magically he lunged through it and killed me. I tried knifing once today for the first time since the first week the game came out and I nuked Skidrow. I got a 15 killstreak just knifing, hid and did the chopper gunner for the rest of the kills. MLC is so overpowered, and its even worse when they have Painkiller. Its pretty much impossible to take them an MLC down when they have painkiller (especially if you like to use the FAL like me)
