I don't know that black mage can really be judged on its current state. To me it feels like they've thrown in the towel as with greased lightning and monk back in 5.4/promise, only this time it's going to be stuck as a failure stateless mess for - what 18 months? The best case scenario would be another miniature rework or flat enochian nerf in 7.3 so people don't have quite as long to associate it with free huge damage but, realistically 8.0 is likely the earliest we'll see the new vision for black mage.

Perhaps if you cast 3 spells of the same aspect in ley lines you'll get one kind of aether, 3 spells of different aspects for another and when you have both kinds of aether any combination of 3 aspected spells for a bigger attack.
