I'm looking to make a dwarf tank, and I was intrigued by the dwarven Throw Your Weight Around enhancement as a way to get a bit more DPS. It is a bit expensive to get to (18 AP), but the abilities you pick along the way will all help you add to your to-hit and damage as well, and the dwarf tree has a lot of tanky enhancements, so I don't see that as a problem.
I'm currently running a pure fighter stalwart defender build with the plan to get all the S&B and THF feats to take advantage of dwarven axes. Unfortunately, I need to get my STR to 17 for the feats, but after this I plan on putting everything into CON.
Has anybody tried anything like this? Is it worth the investment? Would those 18 AP be better spent in the Kensei tree?
