At first, I was skeptical to hear that riot had "revamped" tiger stance, I doubted I would use it, then BAM, tried it in a practice game, jungled with it and to my amazement the damage was way more than satisfying. at around level 5 (when I usually start ganking) I found myself doing way more damage than any character ever should, and alas.

here it is folks.

Pros
Unbelievable damage output after trinity force.
Stun locking galore to make sure nobody gets away.
the ability to take out a carry with minimal effort.
easy quick jungle

Cons
If you are used to tanking with Udyr this build may be a bit much to start with considering i rarely use lifeleech.

Let's talk items.
After much thought as to where I'm going with my build the only viable option was MAX DPS and armor pen, tiger stance grants much needed attack speed and along with the passive is extremely deadly.

I know it may seem a bit much to worship tiger stance this much, but after demoralizing literally every AP character ive gone to gank, i wouldn't play Udyr any other way.

Laning phase
This is where you shine. You will jungle and help lanes until level 5, bear stance is a must, purchase madred's razor and boots, and proceed to gank, ALWAYS INITIATE WITH BEAR STANCE.

Mid Game
This is where you start racking up kills and tower diving to push turrets, with turtle stance this is a very easy task and should be done as so, set up a gank with teammates as close to the tower but not visible to anyone else on the other team, initiate by chasing them back to their tower then have the people pushing with you finish them off.

End Game
If the other team hasn't surrendered yet, this is a good time to take out towers, BACKDOOR STYLE.
Your damage should be borderline godlike and you should be able to solo any other player minus super stout tanks with ease.

::PRO TIP::
When you have phoenix stance maxed out, you should start fights in this order. Bear stance to stun, phoenix until proc then IMMEDIATELY tiger stance. The extra damage from phoenix stance will enhance the burst on tiger by ALOT and also adds to trinity force if timed correctly.

If there is anything i could improve in this build, let me know. Constructive Criticism never killed anyone. Thanks.
