Buffing guns that nobody uses such as the p90

There is many cool looking guns in the game that I never see anyone use because of how hard it is to use. The p90 suffers the most it has too much recoil, low range and it feels like the iron sights don’t match up to where the gun is firing, P90s are supposed to have very minimal recoil and a very high fire rate. I think this gun needs a significant buff in decreasing recoil and a slight improve on range and a fix on the seemingly misdirected iron sights. Likewise I think pistols need a damage buff and the Famas needs better range and a little decrease in recoil.
