Skin Testing

Not sure if this should be on this forum, but honestly, I'd love the ability to test skins and see them in game before I buy. I think we should be allowed to create a practice mode game, and all skins on all champs are available to us. It would just be nice to see what I'm getting into game play wise instead of a splash art or watching someone else do it. Id like to have a feel for the skin, on my own. What do you guys think?
