Unarmed wants high Strength, because the bonus from STR is multiplicative for unarmed, unlike for other weapons. So even at 5% per point of STR, it's very powerful. High STR also works great with Corporeal Projection, making Force Emission more powerful.
Wrestling applies Tackled, which procs the +15% damage bonus of Opportunist. Worth taking.
Taste for Blood also works very well. Even if Unarmed doesn't proc bleed on its own without boots, you can use Nail Bombs for bleeding wounds or just use Taste for Blood as a killstreak feat of sorts.
Bone Breaker and Critical Power are also good, but I dunno if you want crits.
Are the feats in order? If they are, how will you put 3spec points into Blitz at lvl 30?
I've played an unarmed build recently. It was a glass cannon and more crit focused, but had absolutely no problem against Tchort. The only real issue it had was fighting Nagas, Dreads and Psi Crabs.
