I did a quick search and didn't find anything, how this works is. You start out as human out of combat, then you run up to a mob(I did it with a ranged mob) and as soon as you are about to be hit shapeshift. Now if you shapeshift back to caster form DURING the fight you will be human and remain in human. If you wait til after combat ends and come out of form you will be worgen. I've tried with orb of the sin'dorei and orb of deception and couldn't get it to work. I'm hated with goblins so I can't get any noggenfogger to try it.
