In normal queues, how about an option to FF early if the team MMR gap is greater than like 250?

Games with excessive skill gaps usually are so one-sided that they either end pre-20 due to a complete stomp or at 20 with a FF from the lower skilled team because they are down 15+ kills and/or have lost 2 inhibs and haven't even taken 1 of their enemies outers. Games like those are not even fun to play, and often have someone go AFK because it is just a waste of time to continue or the losing team uses the old "push mid we give" message in all chat.

So why not at like 10 minutes in, if the team MMR gap is pretty great (like 250+ or so), an option to FF early is made available?
