I'm sure others said. But I'll confirm it too. :P you need to win games. And sometimes the ranks screw up. Like, swapping ranks with someone if their rank is worse And yours is better. And if they're kind of close to each other. Even though mine is 4500 something. I don't see it as a real thing. Since it jumped from 14,000 to 4000 just from one battle with a beginner. Makes no sense.
