REMOVE MASTIFF ! OMG !

"I was talking about it being easier to use not better. Both guns are fairly inconsistent with the Mastiff feeling worse to me."

I don't know what you do, but I can land my Mastiff shots just fine. Same goes for the Peacekeeper, but frankly I prefer something with ammo that I can actually pick up. Just today I had the occurrence again that I only needed 3 shots to down someone, his friend came to aid, three-shotted him as well. The last guy I took out with my R-99 very easily. My whole squad was doing something else entirely, but honestly it feels a bit weird that I took out an entire squad with a little less than half health left with 2 of the most criticized weapons, without reloading once mid-fight.

That's kinda how Shotguns tend to be though…

"The PK should have greater range and a better chance of high damage shots due to the more clustered spread."

The PK was equally a problem back then. A ton of people - including me - have complained about PK being too powerful. And it was. It deals a humongous amount of damage just like the Mastiff. With the added trait that it can choke it's spread and be a little more effective on mid-range. Both aren't hard to hit, but they hit hard.

If it was for me, both guns would be in the Care Package. Both the PK and the Mastiff are immensely powerful.
