Feisty Chocobo, what class is he and why?

Thanks guys. I made him a healer and find even his low level heals very useful

My chocobo is nearly level 8. I dont hear of many people with higher rank chocobos. I put 21 pts into defender up to the critical boost. Then healer to choco cure. I intend to put the rest into attacker up to the second crit bonus. Reason being, the +hp, +crit etc bonuses stack with each other. In free stance he will have 30% crit bonus, a bunch more hp, two emnity strikes, another attack, a DoT, regen and single target cure. That's pretty diverse.

In action, the heals help him take one to two hits before i pull aggro off him. If he has regen on both of us and uses choco drop, he an sometimes hold aggro for 3 hits. It's not much, but the real benefit comes from being able to specialize him in any of the trees if I start a new class. Whichever works best for what im doing.
