Samurai changes are unacceptable in the current iteration

That's a huge "If", one that's unlikely to be true given their choices in the recent and not-so-recent past.

Which is why they'd have to create new core gsmeplay for every job. BUT! They're more than likely going to homogenize all job roles (except for a few, like BLM) at their core to their simplest form and build upon them that eventually will lead to individualization of every job. How much? I would take a guess at them being at most 25 to 50% more unique then what all jobs are right now. At least if they went that far, Jobs would more or less have an identity that couldn't easily be considered a reskin of one another.
