As much as it sucks, I think it's important to remember that people who first pick this game up, are going to have to unlock each independent job attached to their level 30 class, complete each job specific quest in order to obtain all gear/abilities, and then continue to level to cap. That's actually a lot of work. Getting back to my original point, is that it kind of sucks because in the current community's situation everyone is level 50 already, so you've done half the work, and that includes the first wave of jobs(pld, war, whm, etc..)

Another point to take in, is that new players are going to feel the need to acquire abilities for cross classing, and that again requires a lot of time. Thank god the devs are considerate and this game has a semi faster exp leveling curve, considering we have to level a ton of classes/jobs.
