I am brand new to the game, and upon further research, I'm a little bummed to find that my Rogue will be forced into turning into a generic Ninja late game. I would have much rather stuck to a more Thief archtype who could function as a DPS/Supporting class (perhaps mugging enemies of Potions, and throwing them at allies to heal them).

I really feel like SE need to give some incentive for those who would rather stick to the core classes as opposed to being pigeonholed into a job. A Marauder being forced to drop his DPS in favor of a more tanky Warrior kind of sucks, and it would be nice for a Marauder to choose either Warrior for Tanking, or Berserker (who is more in line with the wild savage fighter theme of a Marauder) as a DPS option. Not only is it a little dishonest for new players who don't know how the system even works (Because someone wanting to be a Sword/Board Gladiator having to run into a holy soldier?), but it kills a lot of the charm of building your ideal FF to life.
