[New Game Mode] One of these things is not like the others.

Essentially One for All, but one person, "The Captain", gets to play a different champion from "the Crew".

Everyone would vote for "the crew" as the current One for All. People could choose to be the Captain, who would then be free to pick their own champion. The captain would be randomly chosen from the pool of people who applied to be captain. If no one applied to be captain, then they would be chosen randomly.

It would add a new layer of depth while still being tons of fun.
