I have been an avid guardian user from beta and it is my favorite gun in the game ever since. They nerfed its fire rate when the game released and it had stay in the garbage can since then.

The gun where it is right now don't provide enough firepower for how much it cost, the firerate is too low and the spread is too high for anything beside headshot hunting. If I don't land head in the first two shot, the engagement is pretty much over in most scenario. The bulldog is a superior options for way less cost. There is no place for it. For headhunter, vandal is also the superior options most of the time.

My suggestion is reduce the spread of the gun when ads or just revert it back to where it was in beta phase. Right now using it is just frustrating, and the only other options are the 2 meta rifles.
