Counters

I beat. Or I bested. I honestly don't know if Zoe has any counters. Perhaps malzahar.

It means you're probably better with this champ than your current rating indicates. Now, I didn't check your profile, and I don't know what your current rating actually is, but if you're a Silver or something, being "better than Silver" isn't exactly the same thing as being "good".

(And anyway, "good" is too vague of a term, but to give you a rough idea with actual numbers: 30% of players are in Bronze; 50% of players are in Silver 3 and below; Gold+ is 30% of players, Plat+ is 10%, Diamond+ is 2%.)
