Talking in game
Well I was playing dota 2 one day and I changed games. You know how Dota has mic chat in game. I think league should add that to the game cause it makes RTS game communication games much easier. I play mainly league but that would be the only thing I do not like league about is that you can't mic chat. If you want to add a mute button for someone who has a bad mic or is mic spamming or figure out something like that. It would probably make teamwork better and it would make better games in my opinion. Please add riot thank you, Put suggestions in the comments please. Thank you. 
side note: Just put a hotkey to talk
