Tank Audit if you please.
Stamina is always a useful stat but if you go through and regem for Haste, you'd have a huge pile of extra Holy Power to work with, more frequent Sacred Shield procs, and of course higher damage.
You're also shy of your Hit/Exp caps, so there's that. RNG is a fickle mistress, I'd recommend being over rather than under.
You're also missing your glove tinker (the important one!), the dodge cooldown is actually a lot more useful than it seems. I'm still planning on dropping Engy for LW... eventually... but Engineering really isn't that bad of a tanking profession this expansion. 2880 dodge on-demand isn't all that bad for a profession bonus, it's just not ideal compared to the Stamina that other professions grant.
