Ok, so all in all its a good gun, stability is nice and all around a good ar. The issue, like a lot of people have noticed, is the exotic perk is so small in effect that you dont notice it. I feel the best thing to happen is when the perk triggers its RoF should go up a noticeable amount to atheons epilogue RoF. With a noticeable stability increase to compensate. Considering how close you have to be to utilize it i feel it would be warrented. TL:DR: exotic per needs to increase RoF to atheons epilogue rate, and stability needs to be noticeable when it procs.
