I'm confused. You're saying precision-based powersets can combo into precision damage, and that's not fair. Ever consider that the powersets are precision-based because they can combo into precision damage? If they comboed into might damage, they would not be precision-based. I think you're looking at it the wrong way. Now, if you're saying that no powerset should be precision-based, that's a reasonable argument. I don't see that changing, but you can argue it.
