Personally, I don't want a wyvern. I feel it held me back in FFXI, as a Dragoon. I really like the idea of some animations involving dragons/wyverns however, that sounds like it would be amazing. In my opinion, Dragoon isn't a job that should be based around a pet, as nice as it was to have the wyvern flying around with you in FFXI. Dragoon was and is unique in it's skillset, and I hope that they keep the job true to what it is.

Just my opinion.
