Accept Match
I think it would be sort of cool if the queue told you what role you were getting before you accept. Personally for me I only find the ADC role to be fun this game, I would really rather not play even a secondary role... I only secondary mid because I know its the most wanted role and usually people will trade with me. I would rather just have the match accept pop up and tell me which role it is sticking me in so I can decline if it's not the one I want to play.
