Hi, been tanking for a few months. Currently my spec allows me to tank any content but i want to start maximising my DPS, i am considering a move to Deep Wounds. I'm just curious if Deep wounds would be better spent than crulety and if i should take talent points out of Shield Specialization. Also does Deep wounds tick threat on targets as well. Any other enchant tips or general advice is also appreciated.
There have been enough posts explaining the 15/5/51 build I think, reading one of them would be a lot better for you to understand. But, if you don't want to do that, then the simple answer is that it's probably the best spec if you want to maximize your dps/threat.
In terms of your gear, try and pick up a little more exp so you can hit the 26 softcap. Hit is a little low and again, try to pick up gear that can bring you closer to 8%. Bear in mind that you should gear for the encounter, so there's no point regemming or using pieces of gear which might get you killed while tanking (if you're still struggling in naxx for example).
One place you can swap gear around easily is your Essence of Gossamer. If you feel you have enough hp for a fight, you can take it out for a threat trinket like the drop from Heroic Naxx (+hit) or Mark of Norganna (+exp).
