Ah I went back through my log and see this now thanks. So the companion doesnt get any of your FATE or quest rewards, or xp bonus either. I was getting 100% bonus on xp and the companions was half of it. So the only way to level companion is to grind mobs or fate mobs. Interesting. I just wish the companions xp bar actually showed how much is needed.

Well there is the open world mob grinding content so many people wanted. Seems the best way to do this is in a party of 4 people and 4 chocobos for a full party and grind FATEs.
