Ideas for the next ARURF

I was thinking of some ideas for the next ARURF. I know that a lot of people really enjoy the original URF and there are also some others who want diversity in their games. So I came up with these ideas that I think might help both sides (ish?)

• The odds of getting a champion that you played in a previous round decrease. If you are lucky and continue to get the champion, the odds decrease even more. It would take about, say, 5 games until the odds of the champion that you got recover. This way, it'll provide more diversity and get rid of the problem where players were getting the same champions in a row.
• Players will get to choose between 2 or 3 champions that are randomly drawn. Of course, the champions for everyone are different. This allows players to at least get a choice to pick 1 out of the 2 or 3. I think this'll help because there are some people who sometimes get things that may not be fun to with and this way, it'll prevent that and also sort of give some diversity.
