If you're so good, just do it yourself: A situation we've all been in

You: I can't play ( X role ) Everybody else: omg fucking noob don't play ranked if you cant play every role

I have a better idea, If you four really think you can play every role perfectly, how about you fucking do it yourselves. How about if you're not willing to work with your team and work around eachothers weaknesses and strengths, then maybe you should not be playing ranked.
