There are 2 builds, the avoidance and the mitigation. The avoidance build will take the least damage on a boss fight - that one's a fact
You can go for the "mitigation" build but it is inferior hence why I haven't put it up but I could put it up if demand is high enough or if we get a boss fight that says it is better for that particular one.
However, with regards to spell damage, I don't feel I need to alter it because the SHOTR buff only does physical damage - the underlying principle is that you stack enough stamina to survive and then get the avoidances, I'm not sure if I've got that line in there so I'll check and add it if not. For the mitigation build, as you posted, hit and expertise are top but seeing as the mitigation is inferior to the avoidance build for all we know of so far, it's not been added.
I will add in Thecks macro when MOP hits because only then does it become relevent, as things are broken at the moment (I myself know I have 11% dodge and 29% parry albeit I have stacked stamina like an idiot for lols)
