Good points, it would work well, perhaps late game sell off, or just pick Wit's End or Hexdrinker as the first item, and replace with Atma's. Thanks for the input!

You should be picking Atma's Impaler with this build, either after the mallet, or as the last item (replacing the lamp). Atma's is totally better then the lamp for you, it gives more armor, and much more damage. You don't really need the bonus crit strike chance, and you'll be missing a free ward, but if you focus on being a dps, atma's will give you the damage you need.

Yes, as the guide says, he is not the best, but as the guide also says, it can work well, and his abilities are useful, even without the scale, with this build.

Full tank Shen is indeed a great option, more than likely the best option, but in some instances this build is the better. Think about this, as the situation presented itself to me last night: Your team has two tanks, you as Shen, already locked in, and an Amumu, who wants to build tanky. So, do you just have two tanks, or do you go tanky DPS, actually doing something as well as being a punching bag?

Srsly, shen is supposed to be a full tank. Not a tanky dps. All his abilities scale with ap. There are many more and way better champs to forfill the role of tanky dps like jax, olaf, udyr and xin
