Wait for the sim to be updated and then figure it out for yourself.
With the nerfing of caster weapons, FT damage, and FT scaling, the value of Mastery looks to be ready to tank. Previously the Mastery was affecting about 65% of my dps (because of the number of spells and strength of FT). When I stop using a caster MH and FT on the MH I suspect to lose close to 2500-3k spell power.
Should we after the patch go for a full reversal and reforge all mastery into crit/hit?
With WF hitting 3x now, might we even try WF/WF again?
