Akiza's motivation for this suggestion is rooted in his/her desire to have the summoner split off from the scholar with the hope that the summoner class will be re-implemented as the FFXI summoner. This will probably not happen. With that in mind, I actually tend to prefer the current system under the condition more classes will have access to multiple jobs. I tend to fall in the camp that getting to the level cap means you've completed the tutorial (SE did give us a nice story), but the bulk of the game is spent doing activities at the level cap. The fact that players will have multiple jobs at 50 isn't a big deal since those jobs won't necessarily geared the same.. In addition, this is probably the best way to bring a duel role system in, which provides more flexibility to players, and if implemented in the duty finder (letting people register for a role with a given class), this would be a good way to reduce queue times.
