First of all, it doesn't have "infinite ammo". It only refills with three precision shots and you can't complain about this "infinite ammo" in crucible because they give out ammo all the damn time. Which means that everyone has "infinite ammo". What makes the black hammer so good is the fact that it chews through strike bosses but besides that, it's just a sniper. Deal with it. Someone would have to get 3 headshots in a row to refill their clip in crucible. Which means that the weapon isn't OP, you just got tripled by a FaZe clan member.
