19 JOBS because I excluded BLU. Nineteen. 3 roles. That's far more than enough to split job complexity while having at least one "easy to master" job per type. Having "braindead" jobs has never been the problem. It's wanting every job to be just as simple (except BLM because Yoshida likes it) so that 'anyone can master it' that is my biggest issue. If they're so against a fundamental aspect of japanese rpgs (trying out different party, gear and skill configuration for specific fights) just because they're afraid some jobs will be "banned" from party finder the least they should do is allow for varying degrees of job complexity so people can find a job they can have fun with. Not literally every player thinks rotations need to be jokes such as 6.0 SMN to have fun. There are players who feel great at mastering more demanding job play and your game offers very little of that outside of pvp.
