I think a simple name change of unranked to ubers and an official ladder for ubers would be good for the community and it would open a new world of legends that could possibly come to pro because they would actually have a purpose. The reason I say change unranked instead of making a whole new game mode is because nobody ever uses unranked, I sit in queue almost 40 minutes at a time waiting for a match and when it comes its usually people using ubers anyways
