Emotion System [Communication]

Emotion system would be great way to communicate without VOIP or other stuff.Coding it would be easy, but animating maybe not that.---- Update:Image what UI would look like ingame:The cursor points where the mouse is.----You could hold Q and there would be circle with different animations you can do like:- Wave- Point forward- come here thing with hands- stop thing with hands; wave both hands forward- bash fist on other hand- facepalm, if someone does something wrong- etc...Moving should immediately stop the animation without waiting.This might be the best way for troll free games with communication.
