"is it wasted movement to use feints when it could be used for actual striking?"

i would say definatley yes. i'm a firm believer that setups/feints are great, but dont just throw something out there thats not going to do anything. why do that? bad. what if you would have got lucky and the feint would have hit them? what if it would have hit and then your second hit doesnt work and then they stab you in the throat and finger fu ck the hole? see that would suck.

i agree with fury that small movements like a twist of the hips could be effective (very effective in sparring) but i still doubt that i personally would use them in a fight.
