I suck ass with STG with no scope.

But Im Too good with the scope.

what do i do?

i dont wanna get 75 kills while im losing my k/d.

In my opinion using an STG44 is just like saying you're too lazy to tap your finger fast. Use a different rifle such as the M1a1 or SVT, and you'll kill people quicker that way. Other than that, just practice shooting walls or play a couple of FFAs to get better + get your kills up.

By the way, you shouldn't be worrying about Killdeath Ratio. As long as you have more kills than deaths, it's good enough. A kill death ratio just tells you how good you are at killing noobs. Doing good in wars, tournaments, and scrimmages determine how good you are.
