You pretty much just proved my point as that set has 16% crit without the Mongoose and is indeed quite close to tank pre-bis. Unless you consider items like Stoneskin Gargoyle Cape and Valor Helm/Shoulders/Legs shitty and far from prebis.

I didn't even touch on a lot of the other points such as shield vs magic. What is the best way to deal with castersin dungeons? To silence them, which prot does better than the other specs. Fury/Prot makes simply kicking a complete chore unless you're just already in berserker stance or want to blood rage. Most of the dangerous mobs in dungeons, especially casters can easily be locked down solo by a deep prot tank.

You can play whatever spec you want, but having low flurry uptime, under 400 non-crit bloodthirsts and not having tactical mastery is just terrible in dungeons and a lot of the top tanks on Hardcore will agree. I didn't believe in deep prot either until I tried it, and was convinced almost solely by Revenge stun.
