Well I'm against it. But not for the reasons you might think. I'm very happy to change up the meta. However I think the nerf is too much, Changing the gun completely isn't the way to go IMO. I'd much rather see bloom being adjusted on other handcannons instead. And if that's not enough then maybe a slight change to the Howl perk. Not a total change to RPM and the exclusive perk.
When nerfing becomes the answer to everything , the game gets really really boring. Which is how d2 was made.
