User blog comment:StrategicMagic/Vayne - Carry? Yes. AD? No./@comment-92.41.62.231-20120820001202

If you want to play an AD carry you need the standard items. Buffing your damage by 2.5 times with one item (IE) is FAAAR better than just attack speed. Getting crits to 100% (or very close) and getting attack speed high (2.5 is not neccesary) is the best way to go for any ad carry. IE, 2 PD's, 1 bloodthirster, attack speed boots and either a second bloodthirster, PD or a black cleaver gives everything you need.
