EDIT: Nidalee visual rework announced! One down, many to go!
RiotNarya (the Riot Art Director) wants the COMMUNITY'S input on who will get the next visual rework! 40 have been chosen, now it's up to YOU to choose who will be next!
Note that a Visual Rework can include the in game model and the splash art.
Someone should start a community driven voting system that prioritizes reworks. We'd look at that for sure. We do separate base champs from skins while doing reworks. That's simply because there are so many skins it's gonna take us awhile. Base champs we can cover more quickly though each splash takes a lot of time!
