Free champions

I've been hunting for a champion for me to main, and man is it hard to have to save up ip for that one champ that you wanna try. I'm suggesting that League players have the ability to try every champion, but only on blind pick or custom games, and they won't get a ip reward. That way I can try any champion, and not waste my time saving ip and buying a champion that I don't like ( im looking at you)
