User blog comment:The5lacker/The crit stacking meta: Why this needs to stop/@comment-5604521-20130408092441

I don't think I've ever seen an ADC rush crit chance without an IE. I personally go IE then PD right after (getting vamp scepter on the way of course) on almost all ADCs I play because their autoattacks will smack harder than their abilities. I do grab a BT and such as well, but getting a PD then Statikk Shiv right after is pointless, because like OP described, pure crit with no damage is pointless.

But that being said, I repeat - I've never seen anybody build pure crit without an IE. Ever.
