You need a talent account.

After you get the talent account, you can set up your talent profile. All talents will start with 100 points. Those points are your life. You get your rank based on your points.

If you win a match, you will gain 1 point, and if you lose a match, you will lose a point, so if you have 100 points and then you lose a match, your points will be 99, and this is how we rank our talents.
