I realize this was a really long time ago... but i noticed that you were looking for a good Udyr guide on DEWO's Warwick guide. I just finished mine, and you can take a lookie if you want. :)

On a more relevant topic, i HIGHLY recommend using all the same runes, instead of having several different marks, several different glyphs, and several different seals. just not a good combination. Also, Fiendish Codex really isnt required for Janna, as she is purely support, and the damage she puts out is just a nice bonus. I would also like to see your Description to be more detailed.

Fiendish Codex can go on Nashors Tooth and combined with Lich Bane ! Or you can start with Meki Pendant and turn it not to Fiendish Codex , but to - Chalice Of Harmony ! Its a personal choice ! Also you want to play aggressively and offensive in the beginning you can start out with maxing Zephyr not Eye Of The Storm - but i prefer the survivability in the beginning :) Its your own choice - but thats the way i like and pown many ***es with her ;)

i pwned with this build

Fiendish Codex, i think is bad here, better will be Frozen Heart :D

I forgot to mention that i play also : Heimer, Morgana and Soraka with tha RUNE Build ;)
