Doing it All on One Character? Possible?

I'd also recommend, if you can bear it, to level like classes together. Such as LNC with PGL, ACN with CNJ and THM, GLA with MRD. Certain classes share a lot of gear, and leveling them in tandem will allow you to save space in your armory system as you can convert for materia gear that you no longer need.

I have a loong way to go myself, but that was my thinking as well. I did end up leveling all of my DoM/W jobs to 15 so that I could clear out the lower level armor that I had been stashing.
