The categories of UR/MP and Powered and such are still too vague for legitimately meaningful distinctions in ranked combat, in my opinion.

If the Ranked system intends to be serious, there will need to be smaller divisors with which characters can be categorised - you can be fairly high on the UR/MP scale and still be matched against someone who barely qualifies for that tier? It's an avenue of thought that at least merits some discussion if the ranked system is intended to be genuinely indicative of skill.
