1 - Spectate game availble for use on friends that are spectating.

2 - This is gonna be really out there, but a search option for a high elo game with a specific champion in it to spectate.

Like, type in "Olaf" and have a few featured games pop up with him present.

3 - Moar featured games. 5 to few D:

4 - If you won't introduce any of the above, PLEASE FOR THE LOVE OF GOD, make it so everyone sees the same featured games -.-

it is absolutely QQ inducing when a friend is like "OMG, I SEE SOMEONE PLAYING MY CHAMPION ON FEATURED, SPECTATE IT WITH ME"
oh..look..i don't have access to the same featured games they do. -.-

5 - Chat enabled by default, instead of enabling it every time.

6 - Something keeps making it so you can randomly lose whisper ability while spectating, you can send messages, receive them, but not SEE the received message. (IE when you exit game, you'll see the received message on the client, but not on the chat window in game.)
