New mode???

So RIOT what if you created a game mode that you play for practice. I know you have the facing against bot games, but what if you just have a regular 5 v 5 and everyone that is playing is there for practice like trying out new champions . Cause it gets a little annoying wanting to try another champion but feeding the other team because you dont understand the champion yet.yeah the bot game helps but its nothing like playing against a real person. So everyone in this game mode friendly or enemy would be playing to practice with a champion they have so its not so serious when you die or mess up or get reported for feeding. its just a game mode were everyone is playing to just get the hang with their new champion but also playing against REAL people and not bots to better the experience. idk i hope yoou look and take this to consideration i don't see what u got to lose.
