@Riot, can we have a Random Button

I have every champion but 2. When I play ranked I only play the champs I like or know how to play. But in normals I try new things like Soraka Top/Bot or Bard jungle. To see what off meta things I can play with champions I would not dare pick in the same position in ranked. But sometimes I forget what champions I own or where they are in the list. But at times I do not care and just pick the champion that my mouse was over. Obviously not everyone likes picking random, but this was a feature from before. And now that we have categories we can pick from a random button to choose between, tanks or assassins,etc. Would help with diversity for those who don't have a preference. Maybe even IP or keys/chest bonus for people who do pick it.

TL;DR Add random button, I usually don't care who I pick but would like it to be different every time I pick.
