It was mentioned before by Kaiden that body unusuals from tf2 would be something to explore. However i feel like something that would be nice to see would be whether or not certain taunt effects that exist there could be used as auras as opposed to unusual effects. I believe having some of these effects would be rather nice since it could introduce more auras into the store, being that currently in the store there are only 11 that you can access. Which among these 11 auras, 2 of them are out of the hands of most players. As an example we have the image posted by Kaiden in the discord of the unusual effect "static shock" and then as well this effect "Pyrophoric Personality"(both uploaded below) These are only 2 examples but there are still others that could potentially be used, and even some that could be incorporated as holiday exclusives.
