I have a suggestion. While description of jackhammer says: "The Jackhammer, despite its name, is an easy to control shotgun, even when fired on full automatic. The popular bullpup design, which places the magazine behind the trigger, makes the weapon well balanced & easy to control." So this weapon is pretty much nerfec comparing to f2, and description says its well balanced and easy to control, why not to make it Min ST 2 for example. I think this could result in good lucky burster with jackhammer build, and it would be good since neither huge perception or sg skill would be needed :> what you think?
