I will never understand how some champions don't get a nerf for weeks or even months while others get hotfixed almost instantly.
Warwick deserves a nerf, he has the highest winrate among all champions with almost 55% for a long time already and there is still nothing on the pbe about him.
Volibear got a buff and his winrate was a bit higher than expected, but still below Warwicks winrate.
But he got his nerf 1 patch later.
Janna also, has 54% winrate right now and these kind of champions should never have such a winrate for how "basic" their skill sets are.
Imagine Soraka had 54% winrate... She would get hotfixed in a day. She sits around 50% right now which is fine.
