I posted it under the buffs post, but figured I would put it in here as well. The new Enchanter buff Night's Endless Terror should be cast on melee dps every raid. It procs a lifetap that does a base damage of 5500. Internal discussions between rogues have noticed a HUGE increase in damage done over the course of an event. If all of our melee dps had this, we should see a big increase in our cumulative dps.
For an example, I parsed out on a Wither and Decay run, it accounted for 1.9mil dmg for me. If all melee had that, that is a huge boost!
