Camille was released after Riot specifically mentioned they did not want to add anymore mobility creep to the game.
I have the dates and quotes to prove it.
Camille suffers from a little problem known as "I'm stuffed up the rectum with an overloaded, oppressive kit designed to do everything efficiently".
Whomever at Riot thought up her design, and even moreso those who OK'd her design, literally did not give any thought as to "Hmmm don't you think we put too much on this one champion and she might be completely broken upon release?".
And she was. Broken. So much so, that they hit Camille with -- I don't know -- something a long the lines of like 12 nerfs over the span of a few months' worth of patches.
There's literally no saving that champ unless they do a complete rework of her kit and remove some abilities completely and put that power back into one or two abilities, max.
