Every season you see the same names at the top of the leaderboards. Is this because they are super lucky and always get better team mates? Or is it because they are better than most players and win games despite having bad team mates? If you want to move up in rating you have to try and play better every single match. DON'T blame your team mates, you can't control your team mates, focus on what you can do better. Try to figure out why YOU lost and what YOU could have done better, if you think you played perfect then you're wrong. As for "stop giving rewards for losing" this is probably the best idea I've ever heard for completly killing off spvp.
