This is a feature that has been talked about for years to help boost player morale, but there was always the concern about giving away gold every game.
Now that we have the XP system, giving away bonus XP every game is a perfect idea. Even 10, 15, or 25 is a small amount that still would provide a sense of, "my opponent gave me free stuff!"
I think this would go big way to making user interactions more positive. LeAppvn t us have an option to make it automatic and have to click to NOT send it. Then users can regulate their behaviors themselves. And when you have a bad game but still get xp, that will reduce the tilt a SHAREit bit!
