My friend uses his feet to play games
My friend was born without use of his arms and is honestly pretty damn good at most things he plays. He just started playing League more seriously after a very long break. He thought it might be fun to start streaming on twitch, and is actually a pretty entertaining guy. I'm sure he is open to getting help from all you pros.
In all seriousness... the game has changed a lot. Give him a watch and help him out!
