Oh lovely. Sign me up as a supporter.
I really wish people would give this idea more thought. I think so many are hung up on class and job names rather than thinking about the ROLE (and here I'm purposely using a different term from class/job) they want to play in parties. Given a proper revamping of abilities, and perhaps a new class or two, players can build a ninja or paladin or whatever just like they remember. Or if they wish, they could build something completely new and wonderful.
So what we really need are revamped class abilities, new classes, more significant effects from attributes, and finally some kind of job title system that would satisfy even the most ardent FFXI fan. Perhaps even some kind of unlocking system for these job names as suggested in other threads.
Would you be against brand new abilities that unlock as new jobs are unlocked?
