I honestly think the weapons are fine, but when they do mess up they try to even out the playing field for other weapons. You can see that with the Ranger AR and the MK assault rifle, they have been evening out the playing field by giving the Ranger more and more accuracy while decreasing the damage to builds on the MK, but still leaving both very usable weapons. (When reading this, just throw the infinity blade, guided rocket, and the OG B.R.U.T.E out the window. Those were completely off balance.)
