First off, don't ever have any expectation to rank unless you are getting shadowdance's into your soul cap, this is doubly true on gorefiend feasts. Next for your iron reaver, you just got hit by a brick of bad rng, on your 37 ambushes, only 10% of them crit - this kills the parse. While one offs are fun to get, I've had plenty of rank 2-10's this tier, its complete luck. Having a consistent set of 85-95% parses means more than the one pull you had 70% soulcap uptime. When you constantly measure up to that level, every pull no exception, eventually you will strike the rng required to get some of those godly parses.
Also, if I'm seeing this right, you cast hemo 31 times on just gorefiend himself, I can understand some of the casts when swapping to adds but on the boss itself that is very excessive. You should try and limit your hemo's to ~8-12 on that fight maximum.
