A solution for the lack of recalls for dated champions and minor scale reworks
Any major champion update, or champion/skin release (above 975) comes with recall animations. However, all non-reworked champions and skins prior to Darius' release, excluding minor updates (such as Maokai, Fiora, Alistar) don't have recall animations.
For consistency's sake (and to add a more pleasant visual aspect to old champions), I would like to suggest making recalls trigger a specific character idle animation. It would be a quick and effective way to bring old assets slightly up to date without requiring many resources.
