I personally feel that if you are raiding at the very high-end, you shouldn't even find the need for Honorbuddy or other programs just because you can out-perform those by playing.
But, then again I will also admit to using CLU and my DK to bot LFR and I usually can pull only 5k-8k less than what I would usually playing. Thing is in this situation you have to move your character and everything anyways, so why not just play the game?
