The whole unarmed specialist feats were just a pointless bunch of crap. If I had a choice between unarmed and ONE bonus feat of choice... wouldn't give the unarmed thing a second thought.
Brianna was an Echani, but her training didn't extend beyond hand-to-hand. C'mon! I never event bothered to have her fight unarmed because hand-to-hand at its best didn't match a lightsaber at its worst.
Same thing goes for great items that can't be upgraded. I would rather have an upgradable vibrosword than the higher end, but not upgradable versions.
