I think I found a build to make Warwick OP again

>Warwick attacks his victim 5 times, dealing a total of 150/250/350 (+200% bonus Attack Damage) magic damage (triggers on-hit effects 5 times)
So I was thinking it over. Since Warwick's ult triggers on hit effects 5 times, the on - hit effect from Wit's End, the active on Titanic Hydra and it's own on - hit effect, Skirmisher's Sabre being overall a item good on Warwick, and the armor reduction from Black Cleaver should deal just about the most damage possible with Warwick's ult. Also the Swifties should help from being kited.
Any thoughts?
