Taken straight from my Priest armoury
OT: I think you're losing out on far too much stamina to gain that little damage. Compare your armoury to this one, for example:
Elypsia @ Stormscale - Community - World of Warcraft
You gain ~4% crit, 3% haste, and 40 attack power. You lose 2500 health, percentage-wise about 15%. It's not enough to survive against teams that have some slight clue as to what they're doing.
If it's just for the fun of getting a lot of crit, you could probably get even more by changing some other items.
