I didnt take this talent at all initially and then as my raid started gearing more and more and my Offtanks started to accidentally become maintanks i decided to pick it up. I will tell you now it was probably one of the wisest investments i made in a while. This talent is the ONLY thing that lets me hold threat on malygos long enough for him to push into phase 2. my fury warriors will get double and occasional triple stacks with a bloodlust and start putting out more damage then is reasonable to try and hold threat against. the use of vigilance on the highest threat (swapping as needed for the top) and the insta-taunt when maly turns to tear them apart are nearly mandatory for the level of dps they are putting out in that situation. i very much approve of this ability and all that it brings to the table.
