Got pretty lucky on the last LFR and Gorgor went with me on his priest, won Ring of the Riven on Hagara, then won Rathrak, the Poisonous Mind from Madness. Apparently it sort of sucks, hard. It has a poison proc rather than haste/crit hit/haste or some other things, and it rarely triggers and when it does the damage is meh. I tried it on end time and it only accounting for 2% of my damage, or around 90k. For some reason I didn’t have an off hand to use with it either so ended up buying a pvp one.
