I think a dragoon job with abilities from the other games like fire/ice/lightning breath attacks, lancet (different version of bloodbath but with mp as well), and superb DPS would be much more fun than playing a dragoon job that just has a tag along wyvern that does the special things for you that dragoon has been able to do by itself in the tactics advance series, and other games. Who knows what other neat abilities the dev team would make up for a wyvernless, powerful dragoon that we'd miss out on if it had a wyvern and needed to be balanced and weakened?
