please sammy lets be reasonable, the power of the gun should be what it is in real life and there are other reasons for putting a suppressor on a weapon.
r1= no flash
r2=no recoil
r3= increase in velocity of projectile (yes about 10fps on avg)
r4=concealing position.
let the weapons be what they are, thats what combat is all about. btw walls do not protect you from bullets. i can take an m4 and kill a man behind an 8" concrete filled block wall in a heartbeat (3.5 sec to be exact) thats how much time it takes to empty a mag reload and fire an additional 5 or so rounds to punch a hole (that is statisticlal). if you are good in the game the high power of the weapon will make no difference either you are good or not. the suppressor will stop me from getting blinded every time i shoot. btw why can't i be able to use my weapon as they do in combat and yes they use suppressors on 249's they also put scopes on them and if you run out of belted ammo you can use mags from an m16, m4 and hk416.i love the 249 in real life and know a lot about it. i would give anything to have the 249 where i can select alt fire and it would fire in semiauto with a scope (it would be a good mod). please for once be reasonable with me sammy and try to meet some of not only my needs but others as well. its not that hard to add a suppressor to the attachment list.
one other thing in your post about hit value is that the hit value for the aug, m4, m16, 249 and g36 all fire 5.56 mm in real life and their hit value should be exactly the same except for the aug it in standard configuration would fire gw pat 90 european ammo and it is not as powerful as our m855lap ball we use, but i would except all the same..
