Why is this a thing?
Community complains about X feature on a champ. Riot doesn't want to nerf said feature so they nerf Y feature on champ. Not only does this not address the problem, it hinders the champ for no reason. In the end, no one is happy. I do not like that Ahri's sustain is being nerfed because people aren't good enough to play around a balanced champ. If you want to nerf someone because of their mobility, choose: Hecarim, Yasuo, or Zed.
