1) not every shield is solar. You should be using a primary with burn to take a shield down anyway 2) they move quickly but not very far and never stay hidden for long 3) maps aren't huge, so an enemy being on the other side of the map didn't mean much. Bh has less recoil and hits just as hard. Special ammo drops all the time. What's asinine is to waste an exotic slot for the sole purpose off ammo regen when it drops off of every other creator you kill.
