Draft Pick Griefing

I'm not sure where this belongs, so feel free to ban/relocate/react any way you need to.

I was duo-queueing with a friend. He is a new player to the whole genre, not just League. As such, he has a hard time playing different champs. We were in a draft mode and declared our champions. He declared Sejuani, I declared Veigar. Out of nowhere, the first guy (support role, I think) bans Seju, and when I call him out on it - deliberately picked Veigar. That kinda tells the guy/gal is toxic as heck, and I really don't want to be stuck playing with a person like that for 20-30-40 mins. Hence, I dodged.

Now, here is the real problem: I ended up being punished and waiting 6mins for dodging the queue. I understand we can't do anything to prevent this kinda thing - humans are humans and all that. I just don't want to be in a situation where my options are either suffer the game with a dou... not-a-nice-person like that, or dodge and receive the penalty. This was a usual draft, now imagine how I'd feel if it were ranked?

I guess, what I'm saying is - can we have a safe way to re-queue? Maybe a vote for everybody, so we can safely leave, or at least a pop-up asking why we are leaving? Sure, it would still give me a 6min penalty for dodging (dodging should not be encouraged) but will give me an opportunity to report the player at fault.

Let me know what you guys think.
