Ding 85 and now for some gearing

In the Twilight Highlands I dinged Pys the deathknight up to 85. Immediately I thought what gear do I need and what reputations to grind, to gear up for heroics and normal instances. What Cataclysm factions are there and what do they offer?

Luckily Wow Insider have a Death Knight DPS reputation guide and a Death Knight Tank reputation guide. well I say reputation, but those guides cover gear from other sources too.

Faction / tank rep / dps rep
Dragonmaw E R
Hyjal E E
Earthen ring R -
Ramkahen E R
Therazane R R
(If not a scribe, Therazane E E)

On that evidence, Hyjal Exalted then Dragonmaw Revered and Ramkahen Revered and Therazane Revered get a good spread of gear for both specs.

Hyjal can be quested to Revered in Mount Hyjal, but they have no dailies so I would tabard them.

Dragonmaw have 5 dailies, so I intend on doing those when I can. Really Dragonmaw can be dailied to exalted.

Ramkahen have 2 dailies, so those should be done. However, since my aim is revered initially, I will tabard them in preference to Hyjal, to Revered at least. Then it will be between Hyjal and Ramkahen and I think Hyjal have the tank items and Ramkahen have the dps item at exalted.

Therazane can almost be quested to Revered in Deepholm, just 1 or 2 sets of their dailies are needed to hit Revered, so ignore their tabard and grind on dailies to exalted if you need to. My DK is a scribe so I can stop at revered.

Finally ER offer nothing for dps but the head arcanum for tanks. I think a half or quarter of honoured to revered is left once you finish Vashj'ir and Deepholm, but they have no dailies, so this rep should be tabarded to revered. I will likely do ER once Ramkahen and Hyjal are revered.
