honestly it would be cool learning each city states leaders style as a job even if they were something like BLU and just small limited jobs for like level 1-50 dual wielding greatswords like a berserker learned from raubahn (after we get the sultana to make him teach us ofc). merlywb teaching us that old dogs can know new tricks with dualwield pistols/other more piratey skills like throwing out an explosive barrel that explodes after a set time. Kan-E-Senna teaching us about how to be an elementalist making full use of the elementals and the elements themselves. i'd have to think about HW onward and if i wanna count like aymeric, lyse, vrtra, etc.. idk who would teach us in Sharlyan or crystarium/eulmore tbh
