Concerning the Vayne nerfs

Vayne Base attack damage lowered to 50.46 from 53.46 Attack damage growth increased to 3.5 from 3.25

Is this the right approach? I feel this issue with her laning stems from the ridiculous AA Q E combo, and the easiest nerf would be to remove the silver bullets tick from e unless they hit terrain. A numbers nerf won't do anything. Riot says they aim to remove "hidden strength" and this is a clear example of that.
