I feel like All Any would be a fun setting for a ranked, where instead of looking at a set rolelist, everything has an air of ambiguity, leading to more unpredictability, and more fun overall. Factions with less members would get the ELO loss/gain adjusted.
IDK, might not be balanced, but would definitely be more fun. Instead of just filling role slots, you'll have to read individual players, which is definitely more fun than process of elimination.
