I hope this hasn't been covered before, I didn't see much on the half-orc in the threads.

I was kind of playing around with the CharGen today and wanted to see if a half orc fighter with only Kensai I was viable if he spent all his other enhancements/feat toward Two-Handed fighting and critical bonuses?

I'm no expert, just a casual solo-er. I played for a few months back in 2010 and then just started back up a couple weeks ago. I was hoping someone with more experience could offer an opinion. Any thoughts, ideas, opinions, hints and feedback appreciated, even negative feedback. Thanks!
