Not much you can do about it, its just the RNG, small set pieces tend to drop in the first 3 or 4 stages of MA though, so you don't need to go through the whole thing each time.
Just do the first few stages, abandon quest exit the instance for 5 minutes, then re enter it should have reset by now, accept the quest do the first few stages and repeat till your luck changes or your patience runs out, which ever happens first.
So I have been trying to farm just the (Waist) piece of this set and literally it has NOT dropped at all. I have been at it for 2 months now.
