I've looked into it very slightly. Pretty much all we have is crafted items and our moonkin pieces to work with.
The crafted pants don't surpass the normal t13.
Moonkin Pants vs Resto Pants (This is fully gemmed and enchanted)
Resto gains: 20 int, 194 Spirit, 14 Mastery
Moonkin gains: 205 haste
Helm:
Resto: 21 Spirit, 15 Mastery
Moonkin: 25 haste
Chest:
Resto: 6 spirit, 174 haste
Moonkin: 176 mastery
Gloves:
Resto: 143 spirit, 8 mastery
Moonkin: 10int, 151 haste
Shoulders (Resto wins.. Mastery : Crit)
So, going over all of this, they are all really close. But if I had to choose, it would be the gloves.
If anyone else has a different opinion, I'd love to hear it. I'm just glad they made some good looking teir this time <3
