It probably suffers from the fate of all red ranged jobs. There is almost none played seriously at high crystal rating for a reason. Add to it that it's probably one of the hardest casters and it adds up. But, to give credit where credit is due, there is one PCT on EU that is within the top 10, and mad respect for it.

I cannot agree with the comparison with contradance though. Chocobastion isn't hard countered by 80% of the LBs in existence for starters. Chocobastion requires a tenth of the considerations that Contradance does, and Contra will rarely if ever catch all the opponents so you'll keep eating damage after, and you'll be half naked because already low HP and out of purify. But this doesn't detract for the points you made that the animation may be too long, etc. I'm not enough qualified in PCT to judge on my end.
