Don't play prot much, but... Is this trinket any good? Got it off a coin yesterday, but from what I understand dodge is our weakest avoidance And I also have the DPS/tank DMC is it better to go with those or tank DMC/Dragon's Blood?
I've passed on it a few times for other tanks, though the static mastery is amazing, there is better out there in my opinion. But it's not bad for an offspec trinket.
As for your current trinket options, I'd go with Tank DMC/dragon's blood, because base stamina trinkets are useful, where as static strength trinkets are not nearly as useful. If you have extra VP laying around, go and pick up the Dominance Offensive/Shieldwall tanking trinket, it's amazing.
