For your shoulders, drop the AP gem immediately. Get a Stam gem.
Also, start Hodir, Shoulder Enchants are not optional if you're serious about endgame working.
Enchant the bracers, even if it's just Expertise(don't do 40stam, won't keep em long enough).
Remove BOTH hit gems from your belt, replace with stam gems.
Socket your boots. Since they are nice, use the +10 all stats or a Regal Dreadstone in them for Meta.
Replace your Fezzik's Pocketwatch A S A P with the drop from ToC reg(easy as hell)
The Black Heart as you will use this almost forever.
Re-enchant your weapon with Potency or the top Agility Enchant.
You MAY skate by ToC heroic but I personally would put you back to DPS for it. Run Reg until you get the Heart, replace the gems/enchants mentioned and you'll be fine.
Also run H AN for Essence of Gossimar to replace the HoL trinket.
As for your talents, you are half-threat/half-kinda off.
For both Ret AND Prot Seals of the Pure(Holy talent) is really not optional. 15% damage on your main damage output is pretty crucial.
For Prot, try
this or
this In your talents you are missing Vindication which is a MASSIVE boost to survivability in that you nerf their AP horrendously. The tooltip is bugged. Also, while 5% crit and 3% damage is decent for threat, 15% SoV damage, and other talents are bigger. You also take Divine Sacrifice, which you can never use. If you use it, you die. If you bubble to not die, raid dies.
In the first spec, you go for Reckoning. You will hear the "boss haste" crap from some people but it's not noticeable honestly. The extra potential multi-hits are very worth it, especially with extra SoV.
The second you go more defensive with Imp Div Sac. This is not for the Sacrifice, but for the 20% damage 100% duration boost of our Shield.
As for Glyphs, drop Shield of Righteousness and pick up Hammer of the Righteous.
And on a side note for Ret, you NEED Seals of the Pure, it is a HUGE DPS loss to not have it. Unless you are PvP for it, in which you are missing a ton of PvP talents anyhow.
Eye for an Eye is worthless, as is Divine Purpose and Seal of Command.
This is the overall best Ret spec. Just drop Glyph of Divinity and Crusader strike, neither give you DPS. Pick up Consecration and Exorcism.
Sorry if I came across condescending, NOT my intention. Just trying to give you the best help possible.
