you shouldn't. you worked your butt off to level 74, you should feel proud using it. i don't think using an SMG is cheap especially if you're running around. If you're camping with a Type 95 or an MK14 at the back of the map with assassin, you should have the right to feel cheap but if you're running around, then kudo's to you don't be ashamed

Use what you like if you are happy that's all that counts really.

I can't believe anyone would say the MP7, of all guns, is OP. When I use it, even with Rapid Fifre, it seems like absolute garbage.

Personally I have little boundaries regarding OP guns, as I'll use any I like constantly. I love the T95 for instance, but the mp7 is a recoilless smg, it takes little to no skill to use, I myself find it too cheap to use, best all-round smg in the game no doubt, but the other smgs can compete with it certain cqb some are better there too, they just require more aiming ability to be as good mid and are clearly less on range with range on. It's like a scar on crack (with smg abilities) & with less recoil.

You know how it is with any of the recoilless automatics. Statistically they may not have an obvious advantage, but you just can't quantify the sheer ease of use. And it is very, very obnoxious to be fighting someone at range and have the flinch totally screw you over just because he didn't have to slow his fire rate to land consecutive hits while you do. That's the factor everyone forgets about.

They're not 'overpowered' per se, but no question they are training wheels for the various children and morons who wandered into the crowd. If you want to use them, be my guest. But don't expect to impress anyone with nonexistant skills that these weapons only exist to make up for.
