I have leveled all jobs/crafts/gathering to 50, got all relics and dl already and the only thing I have left to level is my chocobo.

Currently my chocobo is rank 6. I have got to the point where it takes about 1 hour to get 10% of a level. Now I am grinding where the dark devices fate spawns because there is a lot of mobs that spawn there at a good respawn rate.

Is there any faster way to do this because 10+ hours for 1 chocobo level is pretty boring. Thoughts or experiences on chocobo leveling?
