Considering I'm already at level 50, there's no worry about having EXP lost to the bird. However, it's extremely silly that the chocobo's level scales to yours, whether by level sync or when you switch jobs that is not capped on levels, yet its EXP curve doesn't change.

I get that having a summoned Chocobo is good for people leveling up while solo, but the player greatly outclasses his/her pet at such a fast rate that it's like a cheap version of the Arcanist.
