With the removal of DFG
Ahri's changes has bumped her up to a 57% win rate, and dropped fizz and Syndra to 43% and 41% win rates respectively.
Of course, Ahri got immediate changes because she was popular in the LCS. In reality, Ahri didn't need a buff, she was strong without DFG, she was super strong with it though. Changes to other champions aren't being implemented to 5.4 (which I understand complications arose) so the champions that actually relied on DFG to be relevant rather than the champion who used DFG to be unstoppable will be sad for 2 patches.
I think Riot bum rushed this one a little too quickly.
