As an Arcanist/Summoner, I really have no idea what to have my chocobo do. Should I have my summoned pet be an attacker, and have chocobo tank? Or have my summoned pet be a tank, and let chocobo attack? There's no way to know unless I can test it out for myself and see what works. But, if there is no way to rearrange or reset the chocobo's points, then that goes right out the window.

Not to mention, supposedly this game is intended for people to level potentially every class/job in the game. So, a tanking chocobo might work fine for a squishy caster -- but for a Gladiator or Marauder, it may not be necessary. Once all the people throwing snark at the OP get to this stage of their game, they will be the ones screaming at SE to allow chocobo respecialization.

If they don't want us to retrain our chocobos, maybe there is a possibility of getting different kinds of companions down the road? Or, chocobo breeding sounds great too...
