@Riot... I have a proposition for the draft system...
One thing I see way too often is people that ban out the champion that you were choosing. Not always is it intentional, but sometimes it is.. Anyway, this causes a lot of frustration for others and often leads to queue dodging which is also frustrating.
So, I think there should be a system for somebody to contest a ban if the champion they are choosing gets banned by an ally. If a ban is contested the person that the ban was against can choose to ban somebody else (that isn't a champion that an ally wants to play) and depending on the circumstances:
If the person that contested was going to have a ban turn: Their next turn to ban is replaced by the person that had their ban contested...
If the person that contested was not going to have a ban option: The person that had their ban contested will not have an option to ban someone else...
However, if you had already banned somebody, you cannot contest a ban.
Hopefully, something like this would be useful to prevent troll-banning, accidental ban frustration, and queue-dodging.
