I happen to think that the mounts look cool, far be it from finished, but it adds variety and that's a good thing. I hope that other mounts are hard to come by, but there isn't anything wrong about doing something along those lines... Any argument that having other mounts isn't Final Fantasy doesn't tie into the core of what Final Fantasy really is... And that's an every evolving game. Sure we all have our favs, (FFVI for me personally, so I'm super excited about the magitek armor) but that's what's the games about.

Everyone's entitled to their own opinion, and I'm very happy that the dev teams shows us as much as they do, that is one of the biggest changes to SE in years. Anyway, to keep this short. The saying, "don't knock it until you try it" holds true for any and all updates. And if you have feedback, be constructive...
