Take a look on my prot spec, it's used for both tanking and pvp.

You don't really need seals of the pure, since prot's seal damage is laughable anyway, same with autoattack and reckoning.
Includes every important self-survival talent, and both reduced stun cooldown and pursuit of justice for pvp.
It's fine to tank raids with as well, you just need to switch some glyphs here and there as you need them.
(remove focused shield for 5mans for example, add glyph of seal of truth)
