Accept it isn't terrain. If it was terrain then she would be able to use it to stun you, but she cannot do that because it is not considered a wall. While a statement below says "It is cancelable, but qss is not the way to cancel it," this seems like a very fair statement accept it restrains your movements. If riot wants there to be actual terrain then they will put it there, but as of now, if she ults me and i cannot walk backwards with nothing that is considered terrain behind me, then that is cc. It is restraining your movements. Some people have said that it does nothing to restrain your movements as you can still dash in the area where ever you want, accept that is restraining. If i were not restrained i could dash or flash away out of the area, but I am "restrianed". Also you are not allowed to flash when ulted by her. I saw a Khazix try to jump away from her as she ulted him and he was dragged back to the center of the area, but when i tried to flash it did not drag me back into the area after i blew my flash. It simply did not allow me to flash. You cannot flash when you are charmed, snared, stunned, silenced, or feared because those restrict what you can do with your abilities. There for, her ult IS cc and I will have to disagree with you. You should be able to qss her ult as it is a form of crowd control.
