Well, If you're willing to sacrifice fun for fair, then thats how you get Yi with early game power and overloaded champions like Rakan, Camille and Irelia. No one like to be told they suck, and even few like to have it proven to them, but sometimes you really are just the inferior player, and there is nothing wrong with having that demonstrated to you by being bent over by a 10/0 Zed.
The assassin starts from the disadvantage, gets one victory over you, whatever it is, and your level, the next puts them ahead, and the next further ahead and this keeps stacking over and over. You had 3 chances, now if you want to undo everything the other player worked so hard for, you better be damn ready to beat them, kill them, and use their death window to level the playing feild
