It bothers me how Achlyophage is for whatever reason the only exotic to trade off something for it's [i]own f*cking exotic perk[/i]. Why doesn't Armamentarium decrease your Discipline as a tradeoff for two grenades? Why doesn't Purifier Robes decrease the duration of Radiance? I really don't see why GG needs a decrease in duration just because you get a 4th shot. "B-b-but it instakills people!" Yeah, so does Fist of Havoc and Nova Bomb, but I don't see exotic armor pieces nerfing them.
