Gonna have to agree with TheHos here guardian angel shouldn't be needed on a carry/assassin and a bloodthrister or sword of the divine would be more benefitial then a second stark fervor

but not a bad build over

Yea I fixed the Jungling route... :P

I like it. I just started jungling today, and this is really similar to the build a buddy and I came up with for Jungle Irelia. There is really only a few minor differences in the way I Jungle her.
1) I dont put any mastery points in Offensive Mastery...I know its great for when Irelia needs health using her 'R', but when jungling I drop those 2 extra points to finish off Alacrity and Archmage's Savvy
2) Jungling order for me is slighty different.
3) I like to take my 'Q' a bit earlier, I know it makes more since to take it later for ganks, but I just like to dash at the boss monsters in each camp. lol
4) I wasnt taking Guardian Angel, but I think I might.
5) Instead of a second Stark's Fervor, I'd probably go with a Bloodthirster

That's about it as far as differences...I really don't know if my slight differences are any more or any less advantagous than yours. Like I said, Im a noob to Jungling. Heck, I'm not so sure you would see any difference in them, seeing how similar they are. So with that said, Great build. :D

Edit: I actually do take Guardian Angel now. It's a lifesaver (literally) Soloing Barron. As soon as I hit 18, i bought Guardian Angel (no Stark's or Bloodthirster yet) and went straight to Barron. Had I not had Guardian Angel I would have died, instead I was able to kill Barron as soon as Guardian Angel reserected me.
