When there is a Role you don't want to play - Changing the fill option

Hey everyone,

So I am a support main, but I like to pride myself on the fact that I am comfortable playing in any role. However there is an exception to this, I am trash at ADC. Sure I can farm, in fact I am actually really good at farming. But the mechanical skill in teamfights is just a bit too much for me. So I go into a ranked game, I select support as my primary, then I select fill as my secondary. Then I am stuck on adc.

So here is an idea for everyone who has one role that they DON'T want to play. If you select the fill option as either primary or secondary your other selected role becomes the role that you will NOT get. There would of course have to be some visual stuff so that people who don't read patch notes don't get confused but I feel like this would help out those of us who are comfortable playing 4 of the roles in League. It isn't as though selecting a role + Fill means much. Right now I am just stuck picking support and trying to decide what other role I feel like playing second most.

What are all of your thoughts on this possible change to the Fill option in draft pick?
