I was talking with my friend about beast master class, and we thought it would be cool if instead of beast master as a class, what if they made it so we could use all our mounts as companions? They could add different healer, Attacker and tank skills to each mount. So you could pick how to specialise each companion. Like have your Couerl as an attacker chocobo as a healer and Magitek armour as a tank. With some tweaks to the companion system in general we thought it could work pretty well.
I didn't find the right solution from the Internet.
