I will hijack if I want.
However, I do agree that Jackhammer does not really fit in with other HA.
On the mar, I assume that the 50 damage is split between health and armor, however doing that kind of damage with the same cof as a gauss and a rof that fast, it better have some crazy degradation at range.
it is the difficulty of balanceing slower rof up close makes me want to stick with the JH as NC HA only slightly modified, either with no 2ndary and a tighter pellet spray or with a choke system like the scattermax. Part of the thing with HA seems to be that they use the same ammo as MA weapons however the gun is simply more efficient with that ammunition up close.
