An idea to reduce the Toxic and Tryharder Attitudes.

Very simple. Just only give the player the same amount of Experience points when the game ends, ie, no difference betwen lose and victory. I think it will work, because if you recieve the same amount, won't be reason to win at all costs, except in ranked, obviously. People will focus more in lets fun than win. Only pure tryharder people will keep being like that. What do you think? And yes, I know LoL is a competitive game, but it doesn't mean it must be competitive in all its modes.
