All of the super regenerating exotics need a massive buff in the current sandbox. However, not how you may think. I think they just need to be re-worked as opposed to generating more super energy point blank. It would be nice if they give the same returns they do now but also have an additional perk alongside it that would fit in the current sandbox. For example, Ursa Furiosa could also grant allies an overshield to allies behind the shield and continue for a short duration. Or perhaps grant weapons of light to allies who stand behind the shield for a short duration after the shield is gone. Skull of Dire Ahamkara should regenerate all void abilities similar to the Crown of Tempests. Shards of Galanor can add a brief overshield when casting Blade Barage. Orpheus Rigs is fine the way it is.
