Autofill QoL change
Bring back that experimental role select that was being worked on.
Basically, the design had a primary role button, your second role button, and there was a third button that blocked you from playing any one role, even if you got autofilled.
When it comes to fill, I know a lot of guys who love 2 roles but will deal with most roles so long as they don't get jungle, or adc, or support.
This is banking on not too many people hating support but I really think if that is the case and a fair number of people are ok with supporting, this could make things a lot more pleasant even in the worst cases of autofill.
