Since playing through all of the original story, group content, planetary missions, Fallen Empire and Eternal Throne, I've noticed that there a many different ability colors and styles that aren't available to players in-game. I think that the ability (reminiscent of tunings) to change the color/style of our abilities, without any player advantages other than cosmetics, would be an amazing feature. For example, changing the color of Sorcerer abilities to an "Eternal" color, like Arcann's, changing the stance and animation of Warrior abilities, Like Baras', or changing the abilities of a class to that of their opposite faction's counterpart. These cosmetic ability changes can be earned, or bought/gambled for through the cartel, it doesn't really matter, I would just love the ability to modify my abilities for a little spice every once in a while.
