It is always valuable and you can never really have too much

There is very little reason to stop stacking crit, and a good Disc Priest should be able to pull close to 40% eve isk with decent gear.

Holy: Even with the most recent regen mechanics which brought a nerf to Spirit, and caused Intellect to be a much sought after stat, it may seem that Spirit should be knocked off the top of the list for Holy Priests.

While Spirit is still be all end all for Holy Priests, the usefulness of Intellect cannot be ignored. Almost all regen is based off of your final mana, so the more mana you have, the more regen you will see.

Even your Shadow-fiend now restores mana based on your overall mana, therefore picking up as much intellect as you can is a good idea. It’s always valuable and you can never really have too much.

Not the most important stat for Holy Priests, but still pretty important, as gaining more Crit will allow your Holy Concentration to proc more, thus allowing you to regen more mana.

As a Holy Priest you will need about 12-14% haste. As a Paladin tank you want to tank him at the top of the stairs so that you can grab them with consecrate as they land.
