How did you do it with a 48 healer , sense you can't even start the missions till 52 ?
you all bought in a 48 healers with some 52 + .. if we are talking about the Seeker druid stuff .
which the amount of DMG the thrash does , a 55 24k tank was having issue tanking it when I did it .
only 1 person needs the quest for a group to run it.
and obviously only those with the quest will get the reward.
