First, the Cloaks. (elf RvR)
This is a melee cloak and the % healing crit should instead be %melee crit.
This is a healing cloak and the Melee Power should instead be Healing Power.
Next, the Bookstraps
The healing based Bookstrap needs a change from Melee Power to possibly Healing power or maybe exchange the Reduced armor penetration % with the other Bookstrap.
The strength based belt shouldn't have willpower at all. It would do well with having weapon skill instead of willpower, possibly wounds instead of initiative, and maybe 1% melee crit or AP per second.
Finally, the weapons.
Both of these need a rework. It wouldn't be bad to push them closer to the 2h Melee DPS counterparts seeing as the only type of Warrior priests that would try to go for these maces are either Grace or Wrath, both needing those dps stats for better healing or damage respectively.
Thank you for your time.
