I think I would prefer Spirit Visage getting 20% CDR over boosting its MR to absurd levels
I figure it would be really handy for tanky folks since the 5% CDR from masteries is dropping off the face of the Earth unless you invest in the +5% cap mastery.
That would allow them to hit the cap with Visage and Iceborn, which would be nice.
) and giving it a named passive that it shares with Cinderhulk would be absolutely wonderful.
