Nerfs and buffs are needed to try and achieve balance in the game. Right now, there's an issue in Crucible with Pulse Rifles again,(Specifically, the fast-fire ones like Grasp) and shotguns, but this is due to them nerfing things that kept them just a tier under. I don't think Shotguns need nerfed, the issue is that Sidearms and Fusion Rifles don't contend with them at all, therefore making them way, way too strong, the issue is Bungie doesn't see that and doesn't seem to care, and when it's brought up people demand a nerf rather than an actual solution. Fusion Rifles and Sidearms need to be able to contend with Shotguns in some way, shape, or form, which they don't. The fast fire rate with low impact Pulse Rifles like Grasp of Malok need a major damage nerf. They can three burst you, yet so do the low rate of fire ones. 9/10 times you'll get out shot by someone using a Grasp if you use a lower rate of fire with higher impact. What I don't get is why they can't just make PvE and PvP nerfs/balances separate rather than together. That would solve so many issues we have in this game regarding weapon balance, it may take extra coding and data, but I'd say it would be so worth it.
