ARURF Ban token suggestion

So after the rise and fall of what was a busy URF fortnight I have pondered an improvement I'd like to see. What I am suggesting is a ban token system instead of a re roll system, what this would mean is as you played games each person would rack up ban tokens, and players could spend these ban tokens to stop certain champions in their random pool from being rolled for themselves. This would allow people to slowly eliminate champs they have had enough of playing and slowly zero in on a smaller more enjoyable champ pool. Of course the system would need a few rules or boundaries, like X amount of champions minimum or once all available champions have been played revoke all bans. I don't really know but I do know that I was sick of getting Caitlyn every second game, and on top of this I wanted nothing but to play a single champion alll URF his name was Kled not once did I get him... Not even once. So I really believe something must be done to improve this beloved game mode, if the banning tokens is not an option I would also like to see a decrease in chance getting a champ once they've been rolled for an individual.

I doubt this will be read by many but please feel free to scream obscenities at me in the comments or help me mourn over my lack of Kled all URF, RIP the only thing I actually played for this year....
