Most of 11s jobs weren't much different at level 50. I prefer less abilities that all get used rather than 100 abilities that I only use 6 of. Even BLU only really used 4 or 5 spells at 50 and 1 WS. Also at 75 cap the elemental weaknesses were irrelevant in 11 too. Mages all spammed Thunder V unless the monster was extremely resistant or absorbed it. Now in 11 they spam Stone because it has the best damage/MP ratio. No one ever nuked monsters with the weak element.
