No, I'm not confused. You're saying what i'm saying; the "greater" and "lesser" are going to be closer to each other. That's what I mean by "will be normalized". I may be mucking things up with the terminology since DDO isn't D&D in this regard, but that's what I'm saying.
The difference between the big and little stuns (your term) will be lessened. In today's game the "big stun" is really "big" ... tomorrow not quite so much bigger.
