Make Autofill even a bit better!
Everyone needs to autfil sometimes ( maybe not supports but everyother role) so it is possible that you could choose 1 particular role what you don't want to play in any occassion. To me it's adc and getting autofilled to adc is quite rare, but when it happens it's 99% lost game ( own team needs to win 4v6 then). It would make autofill much better. It's not fun to try a new role when you just have 1 decent pick for the role you get autofilled.
