Ok, if you mean items in my build is jungler items, then most auto attack chapions is junglers. Or if you mean my Mid game is jungler then let me explain better. You CAN (not MUST) go in jungle for blue buff golem or wolfs(lizards, wraths or two golems), for extra gold and exp or buff, on your way to your lane. Im also doing it with my Tank Maokai and Maokai is not jungler champion. If you think this make champion jungler, then all champions is jungler.
Boots of Mobility. I pick this because you are faster on map, you can go faster to help taem in fights, you dont stand in your lane whole game and i think this boots are not only for junglers or roamers.
Teleport. Yea, im too evil to this spell, it is usefull, but im not pick it on Warwick, just like i said in guide I dont pick.
Heal. I dont know why some people dont like this spell. But im must agree, there are better champions that can you this spell. But its usefull in team fights. Can save your life or teammate life. its for those who need that heal for play and i must say im using Heal when im starting with League of Legends.
So, i will edit my Summoners spell section on teleport and Mid game for better understanding. But other i keep unchange, because its my opinion.

Why have you said it's a build for not jungling, then built him like a jungler?
The skill order is extremely odd, and doesn't prioritise one skill...

Boots of Mobility should only ever be used on roamers/junglers...

Edit: Oh, and Teleport is great on WW if he's going solo top. Heal should NEVER be considered over it.
