Hi there Lexus. I use the diamondback and I think its great, not 'crap'. For me, I find it difficult to land headshots with the Amby, so the -15% dmg is already an acceptable loss to me. The damage lost is not particularly significant as I prefer not to run and gun. Plus the DB does not suffer the slower fire rate. The regular revolver is neat, but for me, the ability to surprise a pursuing enemy with stored crits is more useful than random ones. Why not the enforcer? I use the dead ringer, and I have to say that I avoid the enforcer purely out of principle. I just feel uncomfortable having the ability to randomly one-shot people, increased damage, with no downsides.
