This is my personal build for Shen. I'm putting it here mainly so I can update and refine it as I play Shen more. I actually don't like playing Shen as a tank... but what I do like, is being able to save my allies while still kicking ***. Also this build is mostly only effective against squishies, I've aced a fed Cho'gath with it as well... Shen is one of the few Champs who can afford to chase people around the map and take turret fire while still making the kill (and surviving to tell the tale).

Pros:

• Good consistent damage with occassional high-burst
• A tanky DPS with more "tanky" than most
• Highly mobile
• Good utility and duo synergy
• Lot's of crits

Cons:

• Not as durable as Shen players may be used to
• Not effective against tanks
• Vulnerable to mages

More info coming soon. Need to play it more and refine the build.
