Maybe Test Champions?

I think it would be cool if we could test out EVERY champion in Leauge Of Legends in the practice tool, or something players wouldn't gain anything from playing. That way we could get a feel for the champ before deciding on whether or not to buy the champion. I think this would be good especially for those who don't have access to the PBE. Just a little thought, nothing too major. Thanks for reading this post :)
