I don't mind her scaling all that much. If they do tone it down a bit, I'm alright with that, too. One thing I would be okay with so far as changes is removing the party trick that is nearly throwing her E into orbit around the playing field by shooting it through a wall. IMO her ult gives her good enough terrain play, and having to use it for crossing the wall and popping the E off (rather then throwing the E through a wall, then using the ult to buff your Q distance/damage) would make her much, much more tolerable.
Don't get me wrong, it's satisfying as hell to sleep someone from waaaay down along a wall and obliterate them, but it leaves much to be desired from the receiving end.
...of course, playing with good vision and not letting her set up those ridiculous one-offs is always a thing too. Just my two cents, apologies for the tangent.
