Promethium Spurs didn't get a chance to perform with the armor stat changes (and overall sandbox changes) before it was fundamentally changed. With how quickly we can get class ability back now, the original, or at least the first revision, would be more usable. The current version requires the player to stand in place and for teammates to huddle around them, which just doesn't feel good. Plus, we already have a version of that which feels better in the boots of the assembler because teammates can move around. The old version at least allowed the player to change positions, like move up, when they triggered a combination rift. Even if the player using Promethium Spurs was not using the combination rifts themselves, they would still be useful for other players who prefer to fight up close to the enemies. Not to mention the plenty of times a war beast or a thrall get close enough to relocate to and use the combination rift. So the combination rifts should be added back to the exotic, in addition to its current changes, or reverted.
