he is sub par to carry from the jungle you need too much farm.

At top most of the common top choices will beat him however he has alot of potential to be a great top if they toned down the mana cost of his w

As a jungler and a top laner he is probably average.

However, if your team will let you and you have a ap top like Vlad or Kennen, he makes a good counter mid similar to other ad assasins like pantheon and talon where he can use his great killing power and roaming potential to really lay the hurt on people.
