My new Evelynn build

Let me begin by saying I don't jungle. It's by far my worst role. That being said, I love playing . So I play her mid. It's been a while since I played her though, so I sat down and decided to try a new build. Tell me what you think.

I build: , with Alacrity (to go fast), , ,, The is mainly for the CDR AP item for me, but the gold and utility it provides certainly don't hurt. The are of course to go fast. and are also to go fast, especially since charges build extremely quickly with her speed and max CDR Q. gives more CDR, and its passive works well with 's E. , again for the utility, the mixture of AD/AP stats that 's skills scale off, and of course the Omnivamp. also for the CDR, AP, and its passive also works well with 's E, much like .

Thoughts?
