There is nothing you can nerf on the jackhammer that would not change it into a fancy sweeper shotgun. It only fires a little faster, and does a little more damage.
Nerf the hammer, you will have to nerf the sweeper, nerf the sweeper, you will have to nerf the rocklet, and so on and so forth.
I could really care less what they do to it, I just do not want another round of whining about some other crap 'n00b gun' in a month
