They said whenever you get exp from killing monsters, you also gain capacity points. Once you get 30k capacity points, you get 1 job point. That job point can only be spent on that job you gained it on.

I dunno, even if a job is unpopular, this system could make those underpowered jobs much more powerful depending on the potency of the bonuses. It all just depends on what they do and what they provide.

For example, maybe like... the Puppetmaster or Summoner bonuses greatly increase their pet damage output or something. All it takes is the right numbers and there you go, they're suddenly good.
