I have seen this a lot today. I have fought Neeko and I have played Neeko. She feels really fun to play against and really fun to play. I would argue that she is the most balanced or one of the most balanced to come out in a long time. Neeko is a burst mage, and her Q-E combo does not burst from 0-100 like a burst mage is supposed to do. So, that is why her ult has a low CD and high damage. She needs her ult to burst you down fully, which is her job.
Just like Lux, or Syndra or others, I cannot think of.
