it's a cool idea, but Bungie needs to rework the armor lock ability. Out of the five or six games I've played just today, just about every opportunity I've had for a close-quarters kill, I've been denied because of idiots spamming armor lock... even when I have the jump on them. Also, the ability to "cancel" the energy sword's lunge attack and the shotgun's extreme inconsistency (I've had instances today alone in which point-blank shots have failed to kill an enemy and and longer-range shots have made it through shield and health both). Fist combat would probably be rendered pointless against anything but someone else with their dukes up, and if armor lock is brought into play, it'd be nothing but guesswork.
