"A lot of changes boosted Black Mage"

Yep. We traded King of AoE to king of Single Target Burst. Except Dragoons still burst pretty hard and maintain higher sustained single target DPS.

Oh, and Summoners are currently just as good if not better AoE while being on par single target DPS.

And basically every other class isn't !#@^ed over royally by ill timed ground AoE.

Yeah, black mages made out like kings, alright.
