Jungle Ornn?

Anyone tried jungle Ornn? Was nervous when the enemy picked Khazix as that's supposed to be a hard matchup, but that game was pretty easy.

I was following this guide http://www.lolking.net/guides/426364

What I wonder with new runes/mastery combination system is -theyre buffing champs all over the place to make up for the base stats lost from old runes. But how will that affect odd builds that really need a stat that isn't usually what a hero would build? This one really needs the 15% attack speed, because otherwise his clear is too slow. I mean for example I can build like this using the Precision tree because all splash bonuses are attack speed -and then take Resolve as secondary. But I don't know that a lot of the Precision runes are really useful to him.
