Just for clarification, I like the system, not the fact that it's for i90 gear. But it's not without its drawbacks.
+Go in on your best geared job and still be able to roll Need for a lesser-geared job
+If you prefer, queue up on healer/tank to farm these with instant queue.
-You're now competing against more people. Tanks and healers no longer go undisputed, and dps have even more competition.
I think I would have preferred this be done with higher level gear. Leave myth gear available through hunt.
