first off for a BT/hyjal tank ur avoidance stats/block%'s are quite low. and ur threat gain stats are all REALLY high. u need to balance them more to get more avoidance/overall damage reduction. things like picking up t6 gloves over the other enforcement will help. ur block% is quite low. try to pick up smething that has more block rating to help with pushing crushing blows off the table.
Also to help the above along try to find or use a utility trinket. 2 stam trinkets is uauly to much when u could use another for avoidance/Damage reduction.
