No, the point is firefly is not an exotic quality perk. Neither was words three precision shot perk. White nail gave a sniper rifle unlimited ammo. A legendary sniper rifle. Why use icebreaker for anything, an exotic, when you could use black hammer, a legendary, With a perk that would suit an exotic well. Plus why are you complaining? It still refills the mag, it just pulls from your ammo. Go pick up some special ammo or pop a synth, it isn't that hard.
