Yea, this is my thoughts on that though
Pulsar's were totally underpowered. They were worthless regardless of the game mode. Same with Shotguns
Hand Cannons should not have been able to snipe across the maps. Sure, I loved that they did, but honestly, I get why they were changed. AR's were perfect though, if anything, give them a range Drop off (which they did), but they don't need a Damage Nerf.
They just went about fixing this problem in the wrong manner.
