Two dps buffed by power infusion and then on top of that buffed by evoker (with double cast buff) is just too strong of a combo to be replaced by regular dps unless those buffs would be nerfed into oblivion and made specs unplayable entirely
They should probably replace double cast from evoker with something less dramatic and random.
Mage provides the int buff which is double scaling the Aug’s ebon might, is functionally immortal between naturally high vers gear and the vers from aug mastery, provides mass barrier, AoE slows (Even as fire), an immunity, and still has some of the best burst + uncapped AoE damage in the game. Even their sustain is good nowadays with no more rune of power and significantly increased combust uptime thanks to the reworks to kindling(?) and SKB.
