Stun is amazingly reliable. Almost too much so. It seems to never fail when I fight H2H specs. But this has already been addressed.

The thing that I am curious about is how often H2H specs hit me. They hit me so much that disarming a H2H spec is now the last thing I want to do. Even though my hand-to-hand is perfected, I can't parry or shield block fists if my life depended on it. They hit me even more than when I fight a weapon I do not even get to learn in my guild. It is not uncommon for me to get hit 4-5 times a round when fighting H2H specs (granted the damage on each blow is not as high as with a weapon but the sheer volume of landing blows actually makes them do more damage overall), not to mention their 4-5 hit lagging pummeling attack.

I am not sure if this is just my experience but maybe have a look the frequency of H2H specs actually hitting? Or maybe allow other factors to affect the efficiency of punching, eg. type of head gear, size of target (enlarged or shrunk), race (giant vs. gnome) and possibly other factors.
