Gotta agree with epsilon.I'm a lvl.53, a terrible TERRIBLE run/gunner. All of my shot gun accolades are unfinished. Im a sniper and a camper. However. Since adding the Masteron, with proxies, and changing to run/gun on in the NightClub, and Facility I'm owning people. I used to camp/snipe those levels(in TC) for 12-15 kills. Now I'm in the 20's. The Master is simply a devestatingly powerful weapon.
