I like your ideas, but my personal philosophy is that diversification protects you more than a tight focus. For instance, if I stack armor pen runes, I won't have a defense against other things. I play with many different kinds of runes so I can be prepared for almost any circumstance.
The 3% run speed increase is pretty beneficial early game, getting from jungle site to jungle site. Granted, it does taper off a bit late game, but for those early ganks where you don't have 3 or 4 ranks in Blood Scent it helps immensely. Also, WW has enough lifesteal from his passive and Q abilities that he doesn't really need the extra defence.
I have used the Spirit Visage on WW before, and I found that, while useful, I preferred things like the Frozen Mallet. The CDR on the Visage was nice, but if you get the Ancient Golem buff whenever available, it helps you just as much with the CDR and mana regen. Also, items like Frozen Mallet and Warmog's Armor give you a TON more health, something which i personally find more helpful than a little CDR.

Thanks for the suggestions, and again, this build is just my personal philosophy.

Quick runthrough:

why having so many different runes? there should be a few things you prioritize (I think), or do you use it to get to some kind of cap (hit/s at endgame maybe)?

As mentioned before cloth armor is used in the build later.

I'm also wondering why you're going with 18 in utility. 3% run speed isn't much when you've got blood scent. Even though 4% cd reduction may be valuable, wouldn't more def be more useful?

a sugggestion I do like for a lot of life steal/ heal champions is spirit visage, a cheap item giving both cdr and extra healing, which in my opinion is one of the things that people hate WW for.

@Pixie Raah I never even thought about cloth being put into Razor. sadface.
Thx for advice, i guess I just grab Doran's shield for the beginning heallth and health regen.

Jungeling is all about speed! Going dual golem-> ancient golem takes time, also building your boots first increases you time spend on hitting minions ( you have hc for early as) people take cloth because it builds into razor, don't see what the advantage of doran's shield is ( +8/hp regen/5sec= you have ls+slow regen; 8armor: cloth gives 18; 120 health; nice bonus but with 18 armor you should be able to survive (especially if you go tank atts+ utility)

cloth+2potion= 370g
doran= 435g

and the obvious ward that any jungler should have imo and you cant buy... (+90g)

this is just the theory so i won't thumb it down but i doubt its efficiency (time, money,ward)

Merry Xmas
