Physic, multiple times have legitimate solutions and arguments been brought before you, on several occasions I have wondered whether you actually understood, as more often than not it just looked like you completely ignored stuff.
We have tackled the fundamentals, and they do not stand up to scrutiny.

You're defending the indefensible on a matter that doesn't even require "limited jobs" to completely disappear. they just need to be revisioned as many others have also suggested that can be done, or could have been done differently from the start, because if they had enough resources for a job that inevitably would have required further content, unless it was doomed to stay at 50, they could have applied the same on the already existing classes.

Thus, for others who are deaf to reason and don't want to really come to the discussion table, I have only this left to say:

This tragedy...

Greater even than the Eureka calamity... must be undone.

If limited jobs must be unwritten, let them be unwritten.

Become what you must. Become the full job Blue Mage.
