Just an idea: a key(or just game feature) item that once you reach level 99 puts the experience you gain into other jobs. there are a couple limitations I think would be required though: 1) your limit points must be full, 2) it would only transfer the points to other jobs that meet certain criteria ie: the job must be level 99 for example. I'm not thinking of this as a way for people to take low level job(s) and fast level them by going to abyssea and using the experience that comes in there to make massive leaps forward. It wouldn't be fair and the job would be useless without the various skillups along the way. I see it more as being able to keep a job that you worked hard to level at it's cap.
