You lose just about everything except wisdom to AC, (Also there seems to be a "centered" bonus AC also when I look at the AC breakdown)

No Ki Stances, No Ki Attacks, No Ki generated (well kinda useless without the attacks), Ki degrades quickly, No special abilities, No flurry of blows. You turn yourself into a medium BaB fighter with fewer feats.
