Corrected rppm would be :
- arcane : 0.89798 rppm
- fire : 0.35636 rppm
- frost : 1.60126 rrpm
So with 1.6 rppm for Frost mage, it will be an haste feast. Someone on the Class balance thread have say that the use Legendary Meta to do class balance. Why not.
When SimC would be ready, I would test it. Because now, I think that it can change a lot of things. With 26% expected uptime (10s duration), we will be a lot of time far beyond haste cap. I feel that haste values will drop if comparing T15H with and without the metagem.
Another effect would be that Frost Dps will be far better. We can expect to be around Fire and Arcane at the end of the patch.
