New idea for champ rotation

allow players to rent champions to try in non ranked games, give 3 tokens per rotation which can be used to rent a champion to try, and then make it so they can't rent the same champion back to back rotations. its just a harmless feature that may make new players enjoy the game more. thoughts? This also leaves possibilities for new missions as well as you could do things like if they rent the champion they receive 10-15% off of purchasing that champion if they do so before the tokens expire

Edit: the more i think about this the more possibilities they can do, they could even add a reward type thing to determine a discount, ex: im level 16 and rent malzahar, for every game i win there is a chance for the champions price to drop by 2% maxing at 20% you could even make the base rate like 5% chance for a loss and 15% for a win, this will also make players more likely to stick to a champ which will make new comers learn way more about the game cause they wouldn't be as focused on finding champs. There is even more possibilities to include the honor system.
