No, it's called overpowered. Destiny doesn't have crazy perks like other games, such as Borderlands or something similar, they are all minor perks in comparison. What is considered an exotic perk is a small DoT, health starts regeneration after a kill with that weapon, free ammo when KILLING an enemy, etc. These are guns you can only equip 1 of at a time and are some of the best weapons in the game. How is it that a legendary sniper, a gun made for precision, has a perk that grants free ammo on precision hits? Yea, sounds very "niche". Oh and to add to it, it has one of the highest impacts on snipers in the game, so the DPS is very high. I'm not even going to try and explain all of the things wrong with your PvE rebuttal, I'll just hit a few. 1. Strike bosses can be Nightfalls too, you know that right? And Weeklys even. Whether it's solar burn or not, Black Hammer can tear through any strike boss due to free ammo. 2. Black Hammer is great throughout VoG and CE. Templar gets destroyed by it, Atheon gets the same treatment, Hive Majors get 3 headshots (enough for free ammo) and a few primary for a kill, and the impact is even high enough that using it in a situation where you won't get 3 headshots is still very smart. I myself don't go to either raid without Black Hammer even, because you'd just about be crippling yourself to not use it. 3. It also is amazing in PoE. There's stationary bosses, solar burns, hive rounds, and many majors, so you'll get free ammo everywhere in PoE as well. You used to actually be able to stunlock Skolas on solar burn and kill him before mines came up with Black Hammer, because the free ammo allowed you to shoot as long as needed. 4. Who cares how long it takes you? That's completely irrelevant to any argument. I've beaten Crota in under 20 minutes, not sure about VoG but I've been around since September so I can fly through it as well, I've beaten Skolas 10+ times post-patch, it's not hard at all for me. That doesn't mean that many aren't as skilled and have more trouble with it. Many haven't even beaten Skolas to date, while I've ran my friend who had no elemental primary and no rocket launcher through it. Doesn't mean that the gun still doesn't make it easier than it already is. Just FYI, Bungie said that they want guns to be on an even playing field and for none to have drastic advantages over others, only situational ones. Black Hammer has a drastic advantage over every sniper in endgame PvE, which is a major portion of the game itself. The only way I could see it not being overpowered is if it had 6 shots and had to crit all 6, and have a low impact to where it doesn't destroy every high tier enemy in 1 clip.
