why should i have too quit playing the game mode i love because they can't balance guns?

dude i love the g36c, i dont want to the maoning *****. The mp5 is my favourite gun ever and im trying my best but you think that it stands up to the ump? and it doesnt even stand a chance against the type 95; dont come in here saying im ****. its no two burst kill. its one or two HIT kill. so you man up and see the light

what? i give up. its a two hit kill! how is that bad? tell me how!

Im no noob. im 100th in the world for search. i have never used cod forums before. i dont want another one gun game and by that i mean and competitive play eg Gamebattles mlg decerto whatever will be dominated by this. coming in here and assuming im a noob doing bad is wrong, im doing just fine win loss of 4 kd of 2.2 im just sick of one gun in cod games being so much stronger than others heres the list

cod 4 - m16
WaW- M1a1 carbine + mp40
MW2 Famas + UMP
Black ops pre patch ak74u then patched ps of i had gone this 74u needs patching all of you guys still would of gone "noob get good, get on my level stop maoning about guns"
MW3 UMP ( again) + brand new famas the type 95
