Zyra Jungle - A serious consideration

Obviously not something for every team comp or against every jungler, but against those who struggle to invade early (all tanks, for example), I think she could really shine.

This isn't me just spitballing randomly. I know it's only one game, but I was able to take control of my jungle and exert considerable pressure on all of the lanes.

Was there a better build path I could have gone with? Even getting FB'd by a Blitz grab, I was able to come back and clear quickly and without losing much health to become an enormously powerful force to be reckoned with. The plants give enormous objective control, too, meaning my team was basically able to take dragon with impunity since I would stay near full health.

Thoughts?

Edit:

Want to explain my masteries and runes:

AD Marks because life before the plants is tough and it helps a lot with the early clear. I'm going to experiment with replacing these but they seemed to help a bunch.

Armor Seals (obviously) to help with jungle damage

6 CDR Glyphs (5% CDR) and 3 more Armor Glyphs to round out 10% with Masteries and again to help with early jungle damage.

3 AP Quintessences for... damage.

21/8/1 because 3% health is only 75 health given my build and I don't think that's as important late game as the very minuscule amount of mana regen I get from utility. Again something I'll experiment with.

In the Offense tree, CDR and Monster damage, full AD and AP, 5% Bonus AP, 6% pen, and the 21 point mastery. (If I were to move the utility tree point I would put it in the 5% AP on AA).

I'm really curious to see what you guys think.
