If your S2 jungle page isn't incorporating 11 Defense for Bladed Armor and Indomitable, you're not doing it right. Nothing in any other tree will give you as much benefit early game as 11 defense will. After that, you've got options. I'm a big fan of Runic Affinity, and Awareness is good enough on WW that I can see running 19 Utility.
Also, if you really want to hit lvl 6 before being relevant to the team, try his red path. He's perfectly safe that way, it messes everyone up since he's not where a blue path jungler is supposed to be, like, ever, and the timing is perfect. Red, lvl 6, and near mid.
