people always use the "it takes like 3 bullets to kill" thing during arguments on here
the average accuracy is probably under 20%, but giving you the BotD lets call it 20
that now means you gotta shoot 5 more bullets for that one extra hit on average, there are more factors that go into it, but its not just one less bullet in most situations
That accuracy isn't representative of shots in a active firefight though, which I know you said it wasn't all inclusive but I think it merits more than side note. It'll include some shots through walls, sniping attempts, general suppressing fire, blind fire, and shots that you took knowing you had little to no chance of killing the enemy but shot anyway simply because you had a suppressor and knew your cover wouldn't be blown. In an actual firefight I'd say the accuracy is probably upwards of 60-90% depending on the player.
Honestly my thought is that most weapons are used at their optimal range anyway so the suppressor doesn't really make that big of a difference there. Most players know what their actual level of skill enough to know if they will either hit or miss most of their shots at a given distance. There are people who know that certain shots just aren't going to happen and there is that guy who has absurd aim with his AR at distances you can hardly hit with a sniper. Either way the suppressor doesn't make a difference as player 1 passes up the shot if he's even aware of it, and player 2 just downs the enemy in two bursts which still takes less than a second.
Personally I think ARs should take a straight damage penalty of 5 to each distance's base damage. SMGs should have a shorter drop off similar to how it currently works. Sniper damage shouldn't really be changed with the new anti-sniping mechanics. I don't think pistols should have a change either as they typically already drop off soon enough.
