In a post 3.0 world, crit is king.
Here are my comparisons.
I am actually thinking about replacing my T6 chest with a badge robe. (Makes me cry) I'll still be able to maintain 4 peice T6 bonus with keeping my holy T6 leggings on (or I can break it for even more crit with T6 shadow legs) -- I have yet to see T6 bracers off Kalecgos. Running with Badge Robe, T6 Gloves/Helm/Shoulders/Legs for the +5% GHeal Bonus, or run as Disc, breaking that and running with Badge Robe, T6 Gloves/Helm/Shoulders, and Shadow T6 Legs.
Losing that spirit/mp5 is rather negligible when compared to the crit gains, which is pretty significant.
