It's a little disengenious to show fictious MAB/int numbers when the real point of your compairson is the 1.3 multiplier scholar get when they use ebullience with their AF3+2 hat. Take away that and you remove ~23% of the scholar "stats," while the black mage has all those stats under every situation. If scholars used ebullience on every single nuke, drain, and aspir they'd run out of strats extremely quickly. Additionally, if black mages wanted that damage they could sub scholar and get a 1.2 damage multiplier.
Just some other notes:
1. The black mage setup has more magic critical hit rate.
2. They've been given two of the most effective job abilities for survival, breaking the "glass cannon" mold.
3. Blm's have AoE nukes, and AM/AM2 spells (which also means they have double the Abyssea green triggers).
4. Scholars only have one enemy targeted unique spell line, which means they're one of the first jobs to get cut from voidwatch fights.
tldr;
Blackmages are kings of the magic damage hill right now, scholars are on the verge of lolsch.
