If you ask to swap roles...

Don't fucking change your mind.

Much less change your mind about four or five times after the fact.

Much less do this after the bans are decided.

Much less do this after you have already locked in your champion.

Much less do this after I have locked in MY champion.

Much less assume that I agreed to any of this to begin with and do it anyways.

You are begging to have your head collapsed into your chest cavity.
