Her rework was a much needed buff that then made her overpowered due to multiple forms of AP stacking from things like the new dragon buff new passive and rabadons, I think I was able to make it to 1800 ap with her building seraphs rabadons mejais and 3 zhonyas at the time, was also able to get a full 5 dragon and baron buff to, i'll see if I still have the screenshot around.

Shortly after specifically because of Cassio the redid how  AP percentile stacking stacked so they nerfed that and tuned her numbers, as I said in a previous post she is still a hyper carry the just messed with her numbers to make mid game (when she gets a decent powerspike because of passive) less oppresive.
