I noticed you are using T12 helm and gloves for 2pc Sub. I also noticed that using the chest and gloves resulted in easier stat management for myself, and higher DPS on ShadowCraft. I was just wondering why you chose those 2 pieces, assuming you chose them, when you lose a lot of expertise and have to take away from a lot of your crit in order to gain it back.

Edit: It also seems the other Kutta, Grim, etc, followed the same setup when testing out the spec, so it could help them out as well.
