i could not break 1900 on recount.
deemed too low by gm asked if i can improve on that.
my spec 12/6/53 awesome for single target but I have a hard time retaking agro from OT (like on surfang) from similarly geared paly tanks w/3k dps.
Use my spec instead. Rotation should be Shield Slam (shield block up), Revenge, Shockwave, Devastate. Prioritize in that order. I pull 6k on trash and 3-4k on bosses. I do that all without gemming hit and expertise, you might want to also copy my gems and enchants to maximize your character. Expertise and hit are secondary to your rotation being correct. Also that dodge trinket needs to go, grab something with stamina or armor on it instead.
following tankspot guide
your build :
deep wounds3/3 and no cruelty "not enough to warrant taking points out of Cruelty or AttT"
vig is called pointless in the tank guide
as for your glyphs:
all the forums point out that revenge has max priority in tanking rot.
revenge + heroic strike glyphs are called the best for this rot.
vig same issue as above.
I see you advocate 1 point off focused rage i wonder if that is warranted to max out my cruelty or at least 4/5
Also i would replace my glyph of blocking for taunt provided i drop 260 hit in gems and enchants
and glyph of mocking blow for command
