Avatar frames

It'd be kinda nice to be able to delete unwanted avatar frames in exchange for stamina/energy, with the amount gained increasing with higher rarity. Or at the very least gaining stamina from pulling frames. This would be nice for those who simply don't care about frames and are just here for the site itself. That or simply removing frames when you already have them. It funnels it in some way to the stamina, which for a site like this, is just better than a relatively useless rare glowy thing.
