Pros:
Jungler
He can kill very fast
Hes Blood Scent will help your teammates
Alot of attack speed and damage
Lifesteal
Hes very fun
Can solo lane

Cons:
He uses mana, and can run out pretty easy
He takes alot of damage
No slow spells
Can be very difficult to flee with

My rune choice is build on alot of attack speed and armor pene.
The whole idea with that build is starting out with a good damage output, that will improve hes passive that gives him health on every attack he does. So the attack speed makes him VERY HARD to harrash in a solo lane, because he will get his health very easy.

That was my personal rune choice.

Ive heard of alot of people who are going for a little bit of armor, crit and damage. And yeah maybe its good for jungling but i prefer mine :)

My masteries are also pretty much build up on Warwicks damage. The Deadliness and Lethality makes him MUCH stronger. Utility is also a good build but i really like offense for the damage, that also matches with hes passive.

Defense does NOT match Warwick. Warwick needs more damage in my opinion :)

My item build is also based on a little bit of survivability, with the warmogs armor and spirit visage. And ofc alot of attack speed, damage and movement speed that is awesome for Warwick. You can also buy 2 bloodthirster instead of 2 phantom dancers, but i like the attack speed that will be around 2,000 and the movement speed, that increase your escapes for a whole group. remember to sell your dorans shield to some more effective items, when you reach a full bag.

Jungling are pretty much based up on health pots.

first : Cloth armor and 5 pots. Next a Executioners Calling that gives him some lifesteal and crit. after that you can kinda much start up on the same build as me and kick the **** outta the other team :)

My summoner spells are build up on Ignite that is awesome vs champs like fiddelsticks with hes drain. Ignite also gives me a boost in the lower level for some easy kills. Flash can be used in 2 ways:
1: so catch up and enemy that is escaping.
2: To escape from other champions.

that match is awesome!

other summoner spells that might be good :

Ghost
Exhaust
smite for jungling :)

The way to support your team is to use your ultimate on the weakest target that will stun it for 2,5 seconds and then your whole team shud catch up and own that target. When the other teams try to fight yo all back go for all your spells. if one of the enemy team trys to escape catch him up with your blood scent and use your hungering strike. warwick is nice to catch up players.

Yeah so if you follow this guide you will be pretty ******** legendary :) try it out before *****ing :D good luck and go own-wick them all!! :D
