I kind of suck with Rek'sai in the jungle

Anyone have any tips?

I'd like to get better with her, because one of the things I have issues with jungling is that "I'm not omnipresent", so I'd like to think think that Rek'sai can help with that.

For some reason I can't seem to win with Rek'sai in a PvP game, and I don't know if I'm just playing her wrong or what. I'm not a great jungler in general, so maybe it's just a skillfloor/skillcap thing, but I don't know.
