In FFXI, you could have a main class and a sub class. This could lead to some pretty amazing and pretty terrible combinations. You could create a super tank that could take anything the game would throw at it, or a hyper-agile character that could never be hit. Or you could create a white mage with a bronze dagger.

Does FFXIV work in the same way? I've been reading BoB's posts a lot on this, and it seems as though you have greater control over what type of character you're going to play as, though this leads to less specialisations. Can you still combine certain classes to make a really powerful class, or does the game simply allow you to benefit from all the classes you level up in?
