Idk if you'd want that. Bungie balances abilities around exotics a LOT. Look at Titan supers without exotics. Bungie said they won't give Tcrash a buff in pve because it has Falling Star despite the fact Tcrash is the worst single use super without it with a damage of 220K if you include the DOT it has. Bungie also had this reasoning with Geomag and Chaos though since Geo was nerfed and couldn't carry the ability they eventually broke and decided to buff it. There's a good chance if Bungie adds a neutral exotic that a few Warlock supers could end up being nerfed due to it. Though I doubt they'd even add one just for this very reason.

You have 3 exotics that offer increased super damage
