Been working with this gear for a while, but i have notice im falling a bit on agro, sometimes its cuz dont have enough rage, keep using devastate devastate, shield slam, revenge, but still its becoming a real challange to tank t5 ppl. its anything wrong?
Your hit and expertise are pretty low. If you can, pick up the 100badge legs.
You're wearing the dps neck instead of the tanking neck. Attack power isn't going to increase your threat nearly as much as the hit/expertise SSO neck, or the badge neck, will.
I'd also lose the Emyprian Tortoise (your defense is plenty high, and there are a ton of good threat trinkets out there for you). Use your tortoise for fights that require high avoidance, but for threat fights use the Shard of Contempt from Heroic MgT, or the Auto-Blocker from 41badges.
Lastly, you shouldn't be gemming for strength (I'm shocked that you used an epic gem for strength in your tanking set). If you really want to increase your threat, use +10hit rating gems, not +10strength...but honestly, you shouldn't have to do this at all in T5 content.
Looking at your spec, you're not specced for threat. You should have 5 points in cruelty, 3 in Imp HS, and 3 in Imp TClap. If you don't need to have Imp Defensive Stance, then go with the 12/5/43 spec; if you have to have it, then 10/5/46 is what I go.
I have Tank neckpiece, i just forgot to wear it by the time armory updated.
I read about the hit cap, and i noticed my mistake, i got some hit rating gems, and replaced stregth, and i need 30 more badges for badge leg piece. thx for advice
