I run a similar build and have been testing it our for some time. I start with Boots + 3 Health pots. From there I get Berserker's Greaves then rush Malady or Ionic Spark. Then it goes straight to Madred's Bloodrazor. Situational items come afterwards. I run all Attack Speed RUNES for fun.

This is a fun build and I enjoy playing it. I've received some good comments from others when using it. Although, this is a miss or fail kind of play. The damage output is insane and definitely provides a great pusher, supporter and extra carry.

Nice to see a build set for this, Fun, innovative and away from the meta. Might I add that her spells are enough utility already. :D

Yes this is how I see it as well, sure you may be able to rip down squishy opponents. I find it hilarious being able to out DPS a Lee-Sin, but also, your function in the team is to push turrets / provide for support on the side. I didn't say that just because you hit a lot of damage, you just drop the idea of caring about your team completely :p

Ty for the support (:

I think your missing the point Charmquark. Your OH's average 244.5 damage per hit (assuming a 2k hp enemy), 27.5 of that being aoe form ionic spark. that totals around 400 damage per hit. Besides, you spells have a lot of cc, and since you take nashors giving you cdr you get almost her full support power as well.

Naah.
Its just far too scattered. All in all, you have a ton of attackspeed, but besides the OH's you only have about 150 AD, thats not much of a threat in lategame.
"Ohh but we have the spells too!" Yeah, about that. You dont get any CDR until you get Nashors, and the complete build has 90 AP...

As far as damage, it MIGHT be viable if only the OHs would apply to the pix volley. But they dont. So with these items, the only way to make a difference concerning damage is if you somehow complete the build before say 15 min into the game.
