foestrikers boots drop rate?

[Marowit]

Does anyone know how @%*%$ low the drop rate their drop rate is? Because at this point I'm going off the assumption they're like .000000000000001% or it's bugged and they're not on the drop table for some reason.

I've run all three of the low level instances that supposedly drop it 21 times now closer to 50 when you take into account both characters I've leveled solely in instances and have seen at least 10 sets of the DoM set and the rest everything except the boots for the DoW set.

It just doesn't seem right that I'd see so much of the full DoM set but not even one foestrikers boots. so yeah does anyone what their drop rate is supposed to be? because it's either retardedly low or bugged
