The problem with Jungle Kass is that his E really isn't going to be helpful. Requires spellcasts to charge, which isn't a problem in lane, but alone?

It's feasible, but he's got too many other better things for him to be doing, like tearing mid-laners a new one, to be advisable for taking up the jungling mantle.
