Promethium Spur was one of my favorite armor exotics because of the combo-rifts- however in it's current form, it requires a LOT of setup that isn't even consistent in order to make the combo rifts be relevant. Currently you have to be in a rift, get your rift charge back- THEN score a kill WHILE within a rift in order to make a combo-rift. In which even with a Solar, Incandescent weapon with Ember of Searing, AND a Helion that cannot be refreshed via combo-rift; it still is a really tight time to make even a single combo-rift. Which is why I hope that Bungie adds just one thing to the item description: "Gain a second rift charge." And I know some may say that it may be somewhat OP due to this, especially making part of PvP suffer, but I believe that the abundance of rifts are within it's 'power fantasy". Plus, Sixth Coyote and Radiant Dance Machines give similar bonuses, why not Warlocks with their rifts? I think it will help it a ton and actually bring it into relevance even a little- given it's hoops you have to jump through to make it even work minutely. Thoughts?
