I think it would be really great to be able to personalised our moveset.
Being able to change to color of the texture as well, i've seen a ton of dark knight with angelic or paladin glamour. It would be great if they could change the VFX color.

But considering Square excuse for not letting us glamour any gear we want, i think they would hold the same position for letting us have differents animations.
They'll probably say it could confuse new players or ruin class identity.
