I dont think Red Death needs any changes. 2 well placed trigger pulls will kill people in crucible. The problem I think you are having is you are trying to compete with Auto Rifles at close range. ARs will win that fight every time. The Pulse Rifles are the all around performers. Decent at everything, exceptional at few things. You do better than scout rifles in close range, better than autos and hand cannons at long range. Besides, Red Death has a great reload speed and one of the best perks in the game IMO. Kills reduce an already fast reload down to half a second AND starts your health regen? That by itself makes it so that you can hop from one enemy to the next much faster and with a lot less risk than any other gun. Overall, I think then pros outweigh the cons.
