Primus pretty much covered it all. As he stated below, the kit is closer to underpowered than overpowered.

Passive gives great health regen and movement speed, but without her passive both those stats are really low, regen in particular.

Q's permashield is still really weak unless you hit a lot of enemies with it (about the same as Sona's shield), and it will only shield your front line or your carry if you're there when he/she gets dived.

E has the same delay as Rengar's ultimate, and 3 seconds is a whole lot more than you might think, definitively enough time to get killed if you get caught out of position.

Also, besides the fact that her 4 damaging abilities have low ratios (and one of them requiring not being visible beforehand), all abilities dealing damage AND scaling off AP is rather common: Katarina, Syndra, Nami, LeBlanc, Cho'Gath, Kog'Maw, Ezreal, Fizz etc.
