I was thinking of having skins for the companion that can match any mount you may have
For example the coeurl could be used in place of the chocobo as a combat companion. I dont think this would be too difficult since most mounts exist in game as enemies and already have animations for combat (coeurl, goobbue, drake, etc etc)
As for bardings i think they should remain chocobo exclusive since itd take much more time to create and animate them for all mounts (even though itd be super awesome to see an armor-clad coeurl or drake). But maybe there could be skin variants for each mount that can be obtained from rare drops from that specific enemy such as the snow goobbue.
So what does everybody think?
