User blog comment:StrategicMagic/Vayne - Carry? Yes. AD? No./@comment-82.230.71.113-20120820131418/@comment-5287086-20120821030201

Do you even know how AS works? If an AD carry can shut down carries in two attacks, and this AS Vayne can shut down in six attacks, what does that add up to? she built attack speed! Her attacks are at least twice as fast as an AD carry's anyway, so you've made a moot point. Also, with her passive w, she ought to be able to get in a third attack, and because of the health scaling of Madred's and her w, she can not only take down the enemy carry in 6 hits -- she can take down almost ANYONE in six hits.

I liked this article, StrategicMagic - it made a lot of sense. I never really thought that her e spell was anything but utility anyway, so the AD scaling is kinda useless especially with the cooldown.
