Jungle Zyra...
is actually pretty fun! I just tried it in a normal and was surprised by how healthy I was the entire time. I didn't have to base until level 5 and even then I felt that I could have stayed out longer. Yes, I'm sure it's not the most super-optimal choice for a jungler, and yes, it was just a normal (with not so great players, myself included), but I encourage you guys to give it a shot. I really like the new passive and Q, well done Riot.
Masteries are the typical Strength of Ages fare and for runes I used CDR/lvl blues, HP/lvl seals, MPen reds and AP Quints.
