Speech Bubble above champions
Imgur: The most awesome images on the Internet
Wouldn't be nice if Riot added an option (that you can disable) to show player's text in chat also in a speech bubble above it's head. (for exemple : the adc telling his support to engage by a simple 'go' would be much simpler than having to switch eye's focus to different areas of the screen)
Can also include /all chat
Sorry for possible bad english, but i think you got the idea. Also sorry for bad photoshop
