It's insane how you're forced to dodge because someone has absolutely, zero, no respect for your time as well as his and wants to troll pick a champion that he's never played before in ranked.
This is insanity. Please.
Edit: I meant experience. Don't allow people who don't have at least a few games to play a champion in ranked. Though I know that this creates way bigger issues with "ok, so, how do new players play ranked?", "will you have to have 10 games on each champion just to be able to play it in ranked?", "how does swapping work?", I just wanted the team at Riot to be made aware of the issue at hand.
I am not sure what the perfect solution would be.
