Akali result was predictable. The exact same thing was tried with Diana and it broke her too.
Fizz never has a good win rate because high skill cap. I don't think he's actually that weak on live. Small buffs maybe.
Syndra with no DFG is a pointless object. I have no clue what Riot is thinking here. Needs significant compensation, got nerfs.
Ahri was going to be improperly balanced 100%. It was easy to see that either she was really strong or really weak and we needed testing to find out. Will surely get nerfs next patch, not sure which ones though.
