Yeah, so I just did yet another simulation, this time with SimC's warrior tier16H sample profile, so essentially a warrior in BIS gear.
Dodge ~= Parry ~= Crit ~= Mastery ~= Str ~= Sta ~= Hit ~= Exp This is the result that it gave me. This is where someone like Theck *cough Teng cough* could find out where the Mastery breakpoint exists or if there is a certain point where stamina falls off in value. I know Theck had a stamina breakpoints article, but the results where due to stamina gimping holy power regeneration. http://www.sacredduty.net/2013/08/14...a-breakpoints/ Anyways, it does seem that at a certain point adding more stamina and mastery is useless, or doesn't have nearly as big of a smoothing impact and it's actually better to stack dodge/parry even though they are spiky stats.
Granted, with my toon I had just the opposite result, where stacking more stamina and mastery will be the way to go once we get into the early progression of heroics.
