man i remember when *somebody* broke ammo procs the good way, and shadow shurikens were being eaten up in melee b/c they were proccing from ammo despite being weapons, best day of my life
swapping out some equipment will drop your stances. i know weapons will drops your stance, swapping my neck sometimes drop my stances, clicking haste or shammy stats from buff bar drop stances, i think bp and legs sometimes will do it too.
