Reduced surrender vote
For a long time I felt like normal (unranked) games are there only to try out new champs and ''feel them out''. That means that no one wants to try hard in normals, especially if you fail the initial laning phase - the first 15 min. of the game. So whether or not the condition is to have an afk before being able to cast that earlier vote, imho I think that normal games should have this option regardless.
