So... karthus jungle
I bet this will become meta in a couple patches. Ap carry ranged jungler with really speedy clears, good ganks with W, the new jungle suits him really well because his AoE shreds krugs and chickens, and Q does double damage to red and blue. He can powerfarm to his strong late game while pressuring lanes with ult and picking kills, or he can go on a gank spree and get his team ahead. He also takes dragons quickly and has good waveclear to hold lanes and push. I bet when Ivern, Vi, Hecarim and Courage get nerfed he will be OP. His only weakness is that he is immobile and not tanky, but that wont really matter. Ik u dont believe me, but we will see.
and
will destroy him anyways.
