They lack damage and precision. Right now, ace of spades is the only viable option but only because of its perk. 180 rpm hand cannons are miles better because they have no recoil at all, they do as much flinch and they fire so much quickly. Yes, you can kill someone with 3 headshots, but so do 150 hand cannons like Dire Promise. So, yeah, Dire Promise outshines every single 140 rpm legendary. So, please, for the sake of destiny 1 players... give 140 rpm the love they deserve. Make their hitbox bigger, their range bigger and their damage higher. 2 headshots one bodyshot is an awesome choice. Thank you.
