Best ring set after unlimited?

Well, I'm pretty sure they didn't want to have 3rd tier rings, not yet anyway, I mean, it took them over two years, between the release of the potential system and the 2012 anniversary, to release a 2nd tier ring, but they're clearly over that now, since they released all those 3rd tier rings I mentioned earlier in the thread in the last year.

Oh, what 2nd tier rings are available?

I think I missed out something.
