Alright, I'm actually posting this suggestion for a friend of mine who came up with this idea.
Make tagged enemies slow down when they have orbs orbiting them. It'd probably be best if the slow-down stacked. This would provide a good incentive to keep tagging enemies until they are slow and vulnerable to a detonation.
Personally, I give this a +1.
