Even though it would sadden me, i think its a logical 'fix', bosses like spidertanks, sepiks and every other boss with a huge crit is too easy to take down with bh. Just spam the sniper and you are done. There is no other weapon that comes close to this usefulness (not even icebreaker) and is thus unbalancing. With this nerf, you can still do this, but you'll have to move to go and find ammo or synth.
