Ahri
Ahri was starting to finally make a note in mid and disrupted the two to three champs in mid. Betteh nerf her again P_O. All this nerf did was pigeon hole her into a specific starting core, and make it so Zed can run away with 2hp, instead of actually dying.
I'm 90% certain these nerfs had nothing to do with Ahri, as they did you indirectly buffing Zed.
