Why is everyone complainingg about the Vayne change?
If you READ what it says, basically they're taking power away from her Q (meaning IE/Shiv build) and putting it into her W. I thought everyone had a problem with her Q in the first place. It doesn't seem to matter what Riot does you're never satisfied. They're taking away what little early game Vayne had and you STILL have a problem with that.
Yes she will be stronger vs tanks but if someone still tries to max Q first and build the same (IE/Shiv) they won't be rewarded for it.
