^Mp5 doesn't need an increase in it's damage, just remove the delay after switching to it
Just remove that little delay it has before you can aim after you switch to it and it'll be used more again
the delay there is for a reason to avoid the desync the gun causes. basically on other's screen you'll see a player running in 1 place and shooting the gun, if I remember correctly that made the player get almost 0 dmg.
* MP5 buffing is annoying, I feel that it shouldn't be buffing anymore because it's OP now
