Scout rifles and auto rifles need a buff. Other than that, I would leave everything the same. Exotic hand cannons are used more than the rest. They're exotic. They should be

They are also much better than everything else

I don't disagree, but impact isn't the problem. The issue is range. Prime example... Just ran a game where we were essentially getting sniped by the Last Word. The stats on that hand cannon shows that it's range is extremely limited. Same thing with Thorn and it's varying set ups. The different weapon setup should have much greater impact when it comes to trade offs. Want more impact? Then the range should take a huge hit. Same should apply to range. The problem is the minimal drop off when it comes to changing out barrel options and impact / range perks. That being said, I'm not for ruining good weapons. Just make the others a viable alternative. In the real world, high impact hand cannons are absolute shit when it comes to accuracy. If that weren't the case, then there would only be one caliber offered. Everything is a trade off.
