classes are just a relic of 1.0 times

back then a class had 10 cross-class slots and a pretty huge pool of skills to pull from while a job had 5 cross-class skills that could only be pulled from the unlock jobs and in exchange had the 5 job skills to make it fit a party role better.
So you'd stay as a class for the more powerful jack-of-all-trades aspect for most stuff and switch to jobs for structured party content

but now cross-class has been reduced to the point of why does it even exist. Seriously everyone has 10 skills and 10 slots why is setting them even a thing?
and jobs come packaged with a pretty hefty stat boost on top of the job skills, so now not being a job is only hurting you with no tradeoff

so now the whole point of classes has been diminished to nothing aside from arcanist. Which i think was just an experiment in giving classes a new reason to exist and they realized none of the other classes were designed with branching jobs in mind like arcanist was making it a monumental task to retrofit them into something usable

probably just easier to leave it as is with a sort of promoting to jobs thing rather than going back and removing classes altogether.
going back and separating scholar and summoner would probably be more beneficial in the long run than branching other jobs at this point, Would probably be a lot easier for SE to optimize and balance if a dps and healer didn't share half their skills lol
