The Jobs system would basically refine the class for party scenarios to make partying more dynamic.
If jobs are refined for partying, they probably won't be good for soloing, which is why they're being built around the class system. Otherwise it would be FFXI all over again, where you pretty much HAD to party. It was great party dynamics because every job was a specialty, but at the same time made soloing a pain (even if u /whm or /nin). We have to remember that part of the game's appeal is that if you can't find a party, or are just trying to squeeze in a quick leve, you can solo relatively painlessly and get decent xp.
