Capped [Class] =/= Capped [Job]

[Volsung]

classes: a wide collection of skills stemming from leveling at using a specific weapon.

When playing a class you may choose skills from other classes to either play a new creation of your own design or something with versatility.

Jobs: niche predefined playstyles. Cross class skills will be limited, and new skills will become available by completing a quest every five levels after opening the job (starting at 30)

choose a class you want to play. lets say you have a 40 GLA and want to play as a tank. You switch to sword and shield. On top of that you now set yourself to PLD because you have earned it and 2 pld specific skills to aid you in tanking.

you are now a 40GLA playing in your PLD niche role. You wont be able to cross class as much stuff, but you now have added benefits such as the skills you quested. When you earn exp this way it just goes to your class, as jobs arent leveled, but are enhanced this new way.

^ that is how I read everything and what it is sounding like.
