Should losers keep playing?

Winning is ultimately why we all play this game. So if you lose more than you win, why should you keep playing? I'm sure that many of you could come up with some excuse as to why losers should keep playing, but your ulterior motive is that you winners will have cannon fodder. I propose that everyone who loses more games than you win should stop playing League of Legends. Then all of you who win more than you lose would stop winning more than you lose, and you wouldn't like that.

I say all this to demonstrate that Riot needs to come up with multiple leagues. Those of us who are not so good and never will be very good no matter how hard we try because of how we're wired could be put in a B league. Then those players who excel at this game could play in the A league. Yes I know that many of the best players played ranked, but that doesn't prevent them from playing a normal round. The bottom line is that currently B league players who want to play LoL have no choice but to be thrown in with A league players.
