I think IOs solved the wrong enhancement drop issue pretty well. First thing that came to mind is Origin resonance on power pools. Make it so every power pool has corresponding Origin. Now what does the resonance do? Can't buff or add any discount, because that would ruin balance in game and cause a whole slue of problems. Maybe a 0.1% chance for an Origin Insight; Double damage, immediate recharge, ect. With a large font displaying ORGIN EFFECT JUST HAPPENED, or something of that nature.
Alas, I view Homecoming as complete, if the server was left in indefinite maintenance, I'd be happy to just relive memories of playing with my friends on Live. The fact that there is a volunteer Dev team that is actively working on making Homecoming Unique, is simply amazing.
