It seems like it's supposed to be kind of a utility weapon, with the weaken and true sight, but we have plenty of other options that do the same job, or better, like Buried Bloodline or Tractor Cannon. It also does decent damage, but not enough to compete with other damage exotics. Even compared with the exotic we got last season, Choir of One, it falls short. Choir has more damage, more ease of use and versatility, and even has some utility through its destabilizing rounds catalyst. All in all, Slayer's Fang just doesn't feel like it excels enough at anything to justify taking up your exotic slot. Now they could just cram some extra damage into it, but that's the most boring way to buff it, in my opinion. What I'd rather see them do is give it a more defined niche that will give it a useful function and place in the game, even if more damaging options come along. One decent solution would be to improve its void verb access/synergy in some way, but we have plenty of void verb access and synergy in the game already, so while it could be effective in buffing Fang, it's also not the most interesting option. What I think I'd like to see the most is for Bungie to focus more on the Nightsworn Sight part of the gun, and lean into its theme as a hunter's weapon (no, I don't mean the Hunter class). I think it could be cool to have some sort of mechanic where when you have Nightsworn Sight active, you can aim down sights to mark a target, making them take increased damage from you and your allies. It would fit thematically with the way the gun is used to reveal the illusionary anchors in its mission, and provide some unique utility that we don't see much in the game right now. Or perhaps you could gain increased movement speed towards targets you can see with true sight, allowing you to close the gap faster, making up for the short range of the weapon. Or perhaps these 2 effects could even be combined together, letting you mark targets from a decent distance through walls, and then sprinting towards them at high speed, to hunt them down. There's also the possibility of giving some sort of benefit to players for defeating a marked target, kind of like what One Eyed Mask, or Cenotaph Mask do for you. These are just some ideas, but I definitely think Slayer's Fang is pretty lacklustre in its current state, and is unlikely to see much use without some improvements of some kind.
