I got this last night with a group of :
lvl 70 paladin
lvl 66 paladin
lvl 65 paladin
lvl 66 warlock
lvl 67 mage

We did it in one run.
No wipes.
So all in all it was a fun half hour of work and the reward was great for that half hour.
60/70 gold
10 major health potion
10 super mana potion
And last but not least a great weapon for all of us. (i got a holy pala weapon (+160 healing)ofc)
