This build has a lot of potential since it provides huge amount of sustain and has really fast clear speed in jungle. I've tested this build several times, customs, bots, tournaments, you name it. it may seems edgy at first, but you notice it can potentially tilt both teams at once, even yourself if committed correctly.

End game stats in one of the games:
http://matchhistory.euw.leagueoflegends.com/en/#match-details/EUW1/2121912119/203749620?tab=builds

you would want to try and clear the jungle as fast as possible. Once that's complete, you should always try and push your allies lane or Tax the enemy's lane.

Pros:
-Can Tilt enemies.
-Reach end game build very fast. ( average around 00:20 )
-Good sustain.
-Fast clear.
Cons:
-Can Tilt allies.
-Can Tilt yourself.
-Ignite can be lethal for you.

You should try and would your team's jungle to make sure the enemy team don't invade. Always use your team as a distraction while you do an objective so you would have no problem clearing it.

It's all about the mind game.
This build is built to tilt league players, they will mostly ignore the game and concentrate on chat so that they can question the ultimate Warwick build.

The Hunter's Machete and 3 health potions is a really strong combination, it provides good sustain and clear speed in the jungle, furthermore you can out sustain counter junglers with this build by right clicking on them.
When you first back you can change your trinket, but you should save up to buy 6 tears at once in case either players of any side cries.
