Mage vs Warlock itemization

I've been watching the "debate" about Evocation with some amusement. Like most mage issues, this is about feeling inferior to warlocks. And in a way, is more of an itemization issue than a specific skill issue, not unlike the one protection paladins face versus protection warriors.

Simply put, a PvE mage needs more types of stats than a warlock.

Mage:
+Spell Damage
+Spell Hit Rating
+Spell Critical Rating
+Mana per 5 seconds
+Intellect
+Stamina
+Spirit

Warlock:
+Spell Damage
+Spell Hit Rating
+Stamina
+Intellect
+Mana per 5 seconds

Each item has a set amount of "item points" at their disposal, depending on item level and rarity. These points are used to "purchase" stats. Different stats also require different amounts of points. For example, Stamina is cheaper than Intellect and Spell Damage is cheaper than Spell Critical Rating.

If we assume that mage and warlock items have the same amount of item points at their disposal, warlock items will always have superior stats, since the item points are spread between fewer and cheaper stats.

If you are a smart mage who wishes to optimize your damage, it is very tempting to skip mage gear and use warlock gear exclusively, even if you won't benefit from all that stamina as much as a warlock could. Many have done exactly that, and I'm one of them. I'm offsetting the negative sides of this choice with a liberal use of consumables.

In a sense, the mage itemization is also a vicious circle. If you are running out of mana even after all of the tricks mentioned in the original thread and here, you might feel tempted to stack up on spirit, but that gimps your damage. Since you do less damage to the raid boss it won't die as quickly and thus the fight gets longer. Which of course requires more spirit gear for you _and_ the healers.
