Because I don't really see it if she does.
Her passive is reliant on RNG being good to you.
Her Q can't really be played around as it's almost always up.
Her W can only really be played against if you have more than one person with hard CC facing her, which you can't really rely on in lane.
And her ult just renders the possibility of RNG being on your side moot.
I honest to god cannot figure out what you're supposed to do about her outside of farming until teamfights start up and hoping you can coordinate well enough to crush her before she kills any of you. Which is, last time I checked, not reasonable counterplay...
