Aside from side arms all special weapons that have exhumed are useless, either needs to removed from secondary weapon type or buffed, allow you to keep special in mag (side benefit actually make exhumed useful and desired in new meta) or make exhumed apply to all weapons like a universal buff like second wind or ward of dawn.

They should just remove Exhumed, and never add another perk that requires a player to die to activate again. It makes you die, and put your team at a disadvantage, all just to get a worthless increase that lasts for only a short time. The only thing it really does is waste a perk slot for a potentially useful perk.
