Couple things before I begin:
1.) Kill Command is a move that you can use anytime you crit. You learn it at level 66, not level 68 like I said in the movie... sorry about the oral typo there. /blush
2.) I apologize that my voice sounds somewhat congested, my allergies are pretty terrible this time of year.
3.) My Kill Command is keybound to alt-tilde, hence the sound of a frantic jamming of keys anytime I use it.
4.) I was originally going to have a quiet background music track as well (because honestly you just can't go wrong with The Safety Dance) but I decided it was too distracting. So hopefully just my voice by its lonesome can hold your interest. =P
Enjoy and hopefully you can learn something from this, I worry that maybe it's not the clearest video:
