Where's the rest of my posts?!?! Ah.. apparently the bbcode or whatever doesn't like the left arrow I drew into my comment. Let's see if third time's the charm...

I was gonna say Insane in the Membrane, but you prolly broke it down better by going The Exalted route.

I recently replaced my Loremaster title with The Exalted and am now working on The Insanse. Unlike some, I found the Darkmoon grind to exalted to be quite profitable. First off, it definitely helped having a toon with Inscription. I turned in a crapload (understatement!) of Rogue's Decks as well as some BC and Wrath decks. Rather than DE or vendor the crap greens from the turn in (from the Rogue's Decks), I posted a couple of each (stats varied) over a few months time until I sold them all in the AH. On average, I prolly made about 15g each. Crappy stats only brought in 4-6g each, but some of the ones with better stats could sell for 20-30g.

And for the Wrath decks, for the most part, their time has come and gone... But when I did this, I prolly broke even buying decks off the AH and then turning around and posting the cards. Actucally, I definitely came ahead. I prolly bought around 20 Greatness Decks for 3500-4500 and then sold the agility and strength cards for 5-6k. (Timing is everything... Just wait a few days or so after the fair has left and ppl will jump on the cards instead of waiting another 2-3 weeks for the faire to roll back around.)

I can also vouch for Loremaster of Northrend. I've completed this on two toons and just have Dragonblight left to finish for a third. Completing all those quests at lv 80 really fills the pockets!

And coming back to The Exalted and someone's comment about lv 77... The AT is a good suggestion, but I'd also recommend starting the Hodir questline around lv 75-77 (depending on if you can get there / fly yet). My main incentive was to get the shoulder enchants as quickly as possible, but the dailies pay well, too. And while it may seem counter-productive, you may want to consider buying some Relics of Ulduar. They're pretty cheap these days (thanks to all those ppl that get HoS/HoL for 90% of their randoms). Plus if you just buy your way to Revered, you've unlocked all the daily quests at that point and can quickly recoup what you spent.
