Not sure if this is the right forum, but it didn't fit into any of the normal jobs/classes.

I wanted to know if anyone had some advice for leveling your chocobo?

My char is an Archer, so I was looking at the tank or healer chocobo skill trees as those are obviously where I'm lacking. Would one of those be more useful to back up an Archer than the other? Am I correct that you have to choose just one of the skill trees? If you can choose more than one will your chocobo use both autonomously at the same time?

Any advice would be welcome.
