AS boots are stupid on WW. Especially since you get 3 AS items and you have hunter's call. Please get sorc boots or merc treats instead so that I don't get pissed off when looking at it.

Also, wtf are you doing with armour pen runes? WW does almost pure magic damage (Q, ulti and passive are all magic damage). All your items do magic damage.

Looking at your rune explanations, it seems you want to build him with "Critical strike". NO. DO NOT build him like an AD carry. Crit is USELESS for WW. AD is almost just as bad but it has a small redeeming quality with ulti damage (But it is still extremely inefficient, so do not do it). WW is not master Yi. When you pop your ultimate, you don't do crits. You don't use AS. AD WW is pathetic. Do NOT build him like this.

Number 1, and I'm tired of having to say this, do not publish your guide unless it is finished. It will get a ton of downvotes because of that, and deservedly so in my opinion because there's no reason people should have to read an incomplete guide when there are so many other good ones out there. Okay now onto your strategy: why the hell would you not max Hungering Strike by level 9? It does percent health damage and it's your main source of damage other than your ultimate. You do not need Hunters Call that badly before level 13, I mean come on... Also you have zero magic penetration whatsoever, so I'd like to see your magic damage on-hit items do any damage to a tank who has more than 100 MR. That 4% max health passive from Madred's Bloodrazor will be reduced to 2% in a heartbeat and will go even lower the more MR they have. Also just as a general rule of thumb, there is no reason you should ever focus the tank on the enemy team, and your title says it all, and it's just dumb. You are also very suishy with this build and while you're suppressing the enemy tank, their carry is going to chew you up and spit you out, just so you know.

I'm not going to downvote you. I want to help you because I do actually know what I'm talking about here. But I cannot say others are as forgiving as I am here, so before you get those negative votes, PM me and ask me for suggestions, or just look at my own warwick guide for more details. This is just not acceptable as it is right now, but you can improve it.
