It seems a little unfair to lose THAT much time on summoning our chocobos from ranking them up. Ranking them should be GOOD...not bad... It takes SO long to get them enough xp for a rank as it is, I can't imagine how many greens it'd take to go from 9 to 10 with only 16:30 minutes of summon time and that much xp needed.

There's already such little content a chocobo is good for, the least we should get is the ability to summon them for a decent amount of time.
