We have a case of a job where you press the exact same buttons from Lv.50 to Lv.90, namely Summoner. All it does over the levelling experience is add the appearance of a summon or a bigger summon and is pretty bland otherwise.

Frankly standardizing everything done at Lv90 all the way down to where skills originate from to be used in the exact same manner makes for a poor levelling experience for newcomers, as much as we may hate downsyncing.

TL;DR: Just open your skill menu and check if Hyosho Ranryu lights up tbh.
