Shyvana replacement?

So after playing her since the start of me playing league (somewhere in s3) basically, I've decided to give up on shyvana given the next patch (or maybe not but for now riot wants to wreck her early game and not her late game, which is what they should be), I was wondering if anyone had ideas for a replacement jungle that sort of acts like shyvana? Fast clears and high agression in terms of gank are preferable, at the moment I'm playing Wukong and skarner, who I think both have strong ganks, Shyvana was a champ I really liked because she doesn't have super strong ganks but she could farm the jungle so quick that she could scale like a devo jungler but still put map pressure unlike a few other devo junglers I can think of, any suggestions on who could be a replacement to her (I might keep playing her next patch but for now let's keep that as a no.)
