What a let-down. Why even raise them to lvl 20 then?
The biggest problem with this game's dev team is that they spend a lot of time developing systems that have no use in the game.
People have offered countless great ideas how to incorporate chocobos into more content especially now that the lowbie dungeons are getting ever more quiet.
I love the companion system but without any content to do with your lvl 10 or even 20 Choco this is one of the biggest dropped balls on SE's part so far.
