Is the (Shadow)Priest the better Mage in WOW?

[Skandranon]

The advantage isn't in DPS or mana efficiency, its in mobility. Running AoE >> channeled standing.

The ability to run is worthless in PvE, where you'll be AoEing standing still anyway.

Warlocks can out-dps mages in certain situations, but normally that's a horrible waste of mana or talent most of the time.

Warlocks out-dps mages just by cursing and applying attack spells. I'm not sure how that's a waste of mana or talents. Warlocks that are Destruction specced to at least 21 can do it with CoS + Shadowbolt, warlocks that are all the way to 31 can CoE + Immo + Conflag.
