First - remember you need to keep 2 points spare for SA.
I'd probably never use your first spec, it's OK but pure threat spec is needless tbh, spec mitigation if possible because we're miles clear on threat atm.
JotJ is a nice talent to have, you can't rely on always having a spare OT, or warrs stance-dancing etc (4HM, council etc). Divinity is decent, it'll help mainly with HoTs but I'm not sure it's going to have that much effect - it's probably the best talent dump to get down the tree though.
SoR/SoV - SoV is the clear winner currently, waiting on PTR info to find out about the glyphed SoR v SoV, but as it's seal only afaik I guess that vengeance will still be king.
Reckoning MIGHT be useful in 3.1 for proccing the enchant, but we'll see how that ends up tbh.
Imp. devo is a talent that depends on your raid makeup; I'll be dropping it asap come 3.1 as it is effectively just a few hundred ac for me. Also, IMO PoJ beats 2% crit, purely as there are a lot of movement based bosses, and it's a nice talent to have. Also, 2/2 imp. judgement is nice for later on in fights when you have a large threat lead and can switch to prioritizing judgement for the mitigation (yeah, small gain, but handy).
http://talent.mmo-champion.com/?pala...0&version=9684 if SA is in the first 7 tiers of prot, with the SA points coming out of divinity/imp. HoJ; else the two for it are coming out of crusade. I think that the DP glyph will be useless due to stacking iissues, else I'll work that in there.
