Fill minus One
If I take fill I should have the option of taking off one of the roles if I want to. I select fill so my teammates can get what they desire most, but sometimes I just don't feel like playing Jungle at the moment, or ADC at a certain time. I've played the game since forever and I know how to play every role at a high level so I don't care what I get, just that my teammates aren't getting something they can't play.
Why, if I am volunteering to take 2x more role positions than the average player, am I not allowed to take one off if I want? This doesn't negate the purpose of fill. There's a huge difference between Fill and Autofill. Autofill would still apply the same.
