I don't think it needs one, but according to the 10/15/2023 TWID it is getting one: https://www.bungie.net/7/en/News/article/10-5-23-this-week-in-destiny "Young Ahamkara's Spine: Reduced the Tripmine Grenade's bonus health from 100 to 70 and removed the bonus 50% damage resistance. Grenade energy is now provided on ability kills instead of damage with abilities. These changes to Young Ahamkara’s Spine targeted two aspects of the Exotic that we felt were causing issues. First, we want to bring its total bonus grenade energy more in line with other Solar ability-focused Exotics, like Athrys’s Embrace and Caliban’s Hand. This change keeps the amount of energy provided large but reduces how easily it can be gained. Second, we wanted to make it easier to counter the enhanced Tripmine Grenades in PvP by reducing the amount of bonus durability that the Exotic provides. The hope is that a well-placed Tripmine will still offer the Hunter an advantage, but a careless one no longer shifts the flow of an engagement all on its own." While these changes sound PvP oriented, unless stated otherwise I have to assume they will also apply to PvE, which is why I made this post.

I meant someone voted for it needed the nerf

Anybody who believes pvp/pve separation is useless generally would side with nerfing something in a game mode where it doesn't need it.
