Autofill

Hello all. Am I only one or there are other people are pissed of autofill. If we are intending to play a certain role and we get auto filled; why do we have to face penalty for dodging. Isn't it unfair? I play mid main and top; is there rules that I have to know other roles too. Every time someone dodge I am assigned different lanes which I never play and do not want to play, but I have to face penalty for dodging for the mistake that I have not done. What other people think about it? Should there be any option for those who don't want to play other role and dodge instead of being a feeder and get bad kda?
