I've been playing 3 years, and my chocobo is still only Rank 18. Granted, I haven't focused on my chocobo hard core at any point...but leveling is slow, when you are only getting 300-400xp per kill, and to level up you need 8 million or something...you start to feel defeated and wondering what the point of it all is. I am not in an FC, so I don't get to benefit from the joys of people feeding my chocobo when I'm not around.
