Leblanc, Balanced or Broken?

So after the changes made to Leblanc were reverted, I had the pleasure of playing against her again. During these games there were times I felt like I wasn't able to do anything against her. For example me being the idiot I tend to be, I forgot about how Leblanc can cast Q during W so it would land before, and you would get the burst off fairly quickly. The only issue I have with this is it's slightly annoying because they can just hold onto these 2 abilities and zone you off creeps, unless you want to walk up and get poked out of lane. All in all though that's not that bad you just need to play the lane safe and watch for her trying to walk up. However there is one thing I do have an issue with in her kit, that being her current e. The initial spell cast I have no problem with, it's simply the radius of the chain after you land it that I have a problem with. The range of the radius is 925 units so if i'm playing an immobile champion and Leblanc hit a point blank E on me I would have to flash twice in order to almost get out of it. I honestly feel that she is the best if not one of the best AP assassins in the game maybe a little to strong (depending on who's playing her), and just wanted to see how other people felt about playing as or against her.
