A possible and simple way to fix dodgers in URF

I think I can speak for everyone when I say that it's annoying when somebody dodges after you get your favorite champion in Urf. What if we were given the option to keep the champion that we just got rolled? This could decrease the number of dodges, as people will be able to keep the champion instead of having to dodge if they get a worse one.

Some problems I see with this is that it might make queue times longer, if two people happen to keep the same champion.

If someone happens to dodge after you reroll a champion, you can keep the reroll(s) and get a new champion, or keep the champion and lose the rerolls.

Please leave opinions in the comments, any problems that you see with this, or other ideas to make AR Urf better.

Edit: I posted this in gameplay, because I have no idea where else to post it. Sorry for any inconveniences!
