I try to maintain 26 Expertise Skill. Right now that means using x2 Guardian Dreadstones in my gear and eating the Expertise Food, which puts me right at 26 Skill. I made a list of the available expertise gear here: http://www.tankspot.com/showthread.p...r-List-for-3-3
Though Hit is nice for threat it's not a primary concern. I just take what I get in the form of equips on gear though the natural course of upgrades. There happens to be a crap ton of it on most ICC gear.
There is something so appealing about backhanding someone across the face with a shield.
