I believe you have enough defense to swap those 16 defense rating gems to 30 stamina gems, if not; enchant your shield/chest with defense. If you dont need def enchants on either, put 275 health/10 all stats on chest and 18 stamina on shield.
Enchant your cloak with armor, maybe gloves also if you dont have any threat proplems.
That 20 parry gem is bad, you shouldnt gem for pure parry ever. If you want that socket bonus there go with dodge+stamina / agi+stamina.
Level up your blacksmithing for lovely 2 free sockets.
Spec for improved demoralizing shout and remember to keep it up.
