Akali, Fizz, Kat, and Zed are pretty much permabanned. I don't ban because I play Mid Fid and wreck all 4 of them lol, but that's besides the point. But, instead of champs that are permabanned being looked at, they want to nerf a champ that is hardly played anymore. I honestly can't remember the last time I have seen a Sona played with the current supports of Braum, Morg, Leona, Thresh, or Janna (most common that I see), but instead they want to nerf Sona's damage AND MS. MS wasn't a huge nerf, but power chord was 10%. So, they are nerfing a weak champion instead of the stronger ones that are always played. That literally makes no sense and you don't need to create a million dollar Moba to understand that.
I am not a doctor, but if I can't walk on my leg I know something is wrong with it.
