Here is a little trick: provocation got much hostility,so if you change the cd value to 0,you can take agro on a boss and his drops easly...
Here is the little story how i discovered it :D :
I discovered it a few years ago,when my friend wanted to help me to lvlup and the lvl difference to get exp in party was too big...I learned provocation to get more hostility,and even with the normal cd,the mob was attacking me,and drops was mine! :)
