It is a bad game design if people have to run to the internet to get important core information about decisions in the game.
A bad design choice in one area doesn't justify the same poor choice in another.
The design of the game allows people to play every class type on one character.
Different classes require different chocobo classes while leveling.
People want to be able to experiment with the different classes to find the right fit for their playstyle.
The most logical assumption a person could make based on the all-classes-one-character game design is that a balanced chocobo would be the optimum choice.
The current setup only makes sense where you could own multiple chocobos or can have different chocobo specs depending on class.
