Why I think fleet footwork and overheal is way too strong. 8.2

This is after the vayne nerf where her W damage goes down at early level and some tweaks to her Q and R. I took her jungle against an enemy udyr, which in retrospect was not the smartest idea, but it worked surprisingly well. Vayne was able to still clear the jungle with a respectable speed and kept her health above 50% at all times thanks to fleet footwork alone while preventing udyr from counterjungling. For a champion that was not really intended to jungle, just this keystone alone made it viable. I think it may also work with draven jungle as well, but I don't own draven nor possess the skill to play him well to test it out. If it does, we may see a new meta of marksman junglers.
