This feels like a suggestion that is fairly unlikely to be implemented, but with the advent of Heavensward we now have a race, or at least one off shoot of it, that is strongly associated with horses. I've actually been getting into the spirit and trying to roleplay a bit, going as far as to change my character's name.

However, if I want to say - level up alongside my mount, I am stuck with my chocobo, which is a little vexing. I suppose I could just name my bird Jungsai and 'pretend' but...

Anyway, I've heard rumors about possibly adding Summon glamours to Summoner, so that you can change the actual appearance of your summon so you're not stuck looking at Garuda all the time. I accept that these are just rumors at the moment, but if they are implemented, something that allows the alteration of your companion's appearance would be super cool, I think.
