Adc zhonyas??

I wonder why this isn't a thing. You've got assassins with good escapes and you have mages with good escapes. I find it total bullshit that mages like Leblanc, Vlad, fizz, ahri...have great escape tools aaaand get a flipping zhonyas to wait their cool down down till they can spam their escape again if they failed the first time. Tanks get a defense perk with a GA. And as an adc you really can't do crap against it. Actually ad carries don't use the ap items and a zhonyas doesn't benefit them at all. And they don't have the life total for a GA to matter. And lucian and graves probably have the best escape but it's no where near what a mages is. I'm saying why can't an adc get a zhonyas type item that actually helps them attackspeed or damage wise???
