for any one that's interested here is a calculator to tell you how much damage you should do with a weapon. just select the weapon type from the drop down menu, input the impact (found from destinydb) the attack value, your lvl and the mobs lvl, and it'll tell you an approximate damage dealt. https://drive.google.com/file/d/0B_FJgcDQ1B8qd2Rub1dKTmJxMDA/view?usp=sharing
