Trial Running Champions

I Don't Post Too Often, Forgive Me If This In The Wrong Section.

So, we all know the weekly rotation, but what about being able to trial run a champion for roughly 7% their cost? The trial could give them 24 hours with the champion and after the trial is over, they would need to wait a certain amount of time before they can trial another champion.

This would really fix people waiting ages for a champion to be in the free rotation just to test if they like the champion or not, and would also save people from wasting their 3 refunds after realizing they hate a champion, the game play, and only got him/her for the looks.

Any Thoughts On This?
