Pro cons amazing solo can take on pretty much any champion 1v1
great creep farmer can stay in lane or jungle for a long time with lifeleach and proc from wiggles
still pretty tanky

Cons ur team will rage but then again who cares you dont play it for them

a Good trick to jungleing with this build is since u have good survivability and speed and damage output

Your able to keep up with mid if not past them in levels very easily and you can counter jungle with rammus as well u dont always have to start at blue buff remember that

easy mode farming easy
