If you're Yaulping to med anyway (to avoid sitting agro), you might as well be swinging something...
If you've got Dawnfire (vs. undead) or a Rod of Dark Commandments, you might actually proc early and get agro over a warrior whose taunt fails. The ratio on this is pretty insane for the Luclin era.
In interesting idea but, like so many, obviated by the preference for newer, l33ter gear.
