Check Brightforge on Shadow Council if you want to see the gear and spec.

A couple of things I've noticed over the course of the weekend: This is a far superior out-and-about spec. Where as me previous Prot spec would be sitting OOM most of the time (not that important when you have a posse following you, but still...), now if I open with a Judgement I generally stay near full mana, or at least operable.

As far as damage goes, I've come to realize this is a very particular spec that won't work for everyone. Why? Because you need all your melee raid buffs before this spec really starts spitting out damage. Given boxers tendency to go with caster heavy group compositions, prot will generally be the better way to go.

That said, until I've taken down Archavon and Noth tomorrow, the biggest thing I've killed is Thrym in Zul'drak. (600k HP, hits for 3-4k) I don't anticipate any problems, but we'll see.

Edit: Oddly enough, you can even use a near 969 rotation with this:

/castsequence reset=combat Judgement of Wisdom, Crusader Strike, Consecration, Shield of Righteousness, Divine Storm, Crusader Strike, Judgement of Wisdom, Shield of Righteousness, Consecration, Crusader Strike, Divine Storm, Shield of Righteousness
