Someone should try a five prot paladin group.
Five paladins with 6/3 consecrated in flame (10 different consecrations at once boyyyyy).
Five paladins with hand of the protector.
Five paladins with last defender (at 23 targets they would all have a baseline 50% damage reduction/damage increase passively).
I feel like that shit would work so long as whoever had threat never got one shotted during the mass pulls since he could just instantly go back up with several different hands of the protector hitting him over and over with its short CD.
