@Meddler DO NOT nerf riven, nerf conqueror
She gained 5% wr overnight because of the rune, she was at 50% wr (49.9% actually) before this patch.
Shes not overpowered, the rune is, go look at jax/olaf/azir stats, they all also massively increased overnight (jax at 54% wr, azir gained 10% wr, etc).
Nerf conqueror, not the champs.
If you want to nerf an actual OP champ go ahead and nerf yorick, whos not abusing any rune but just straight up beating everyone top.
