I'm technically wasting an attachment by using sleight of hand, BUT I mostly play for rushing clips rather than nukes or kill streaks. The lightweight silencer gets overlooked by most players, including me. However, if you're constantly in CQC situations, it's not a terrible choice. Us old heads have been dealing with the -25% damage range reduction since COD 4.
Also, I'm not a toxic player (shooting bodies) but I can't stand players hiding in one building for streaks. I grew up watching DyingSoldier and LastNameIsDredd so that's how I play. Feels boring to play passively.
