Erm this is a partial jungle build Vieke.

Hence the early Madred's Razors, so therefore it is better to max Hungering Strike rather then Hunter's Call otherwise you'll end up dead.

The rest is simply for critical and damage.

Isn't it better to level Hunter's Call before you max out Blood scent.
I mean, THe build is about the "Right-click" and not about the procs, so You'd have more Right-Clicks in a shorter amount of time.

A second Phantom Dancer would be a good final item as it will kick the critical to 90% and also add 15 movement speed making Warwick quicker to kill someone before they got to base or away.
