Especially in the case of an undergeared tank, one you're likely to rip agro from but also one who'll need the healer to actually work to keep them alive, it's often a choice between reducing your agro or keep it for when the healer will need that Refresh. So for physical ranged, agro reduction gets another layer of complexity.
