Since one can not change careers, I don't want to see Jedi as a career. Having Jedi as a Universal Specialization would appeal to me more.
Gand, finding his calling and not being able to become a Jedi due to not being able to change careers seems odd. Sure, he could take one of the specializations, but at a higher cost and would still have to 'fudge' his career to call himself a Jedi.
Don't see why. You are whatever you call your character. A career does not define what you call your character anymore than a spec does.
The game will need to accomodate people that want to characters that come to Jedi-hood later in life a la Luke (take a Jedi spec) and characters that start as Jedi a la Obi Wan (take a Jedi career). Jedi is just as iconic as bounty hunter, soldier or smuggler. FFG chose to design the game around careers and specs. I doubt that will change with Jedi, one of the most recognizable qualities of the setting.
