Fourth: When the enemy faction controls the Warfront, you get access to 11 quests that allows you to trade materials for AP and honorbound rep. This is huge because you get 750 AP per turn in and 500 rep per turn in which gives you a total of 8250 AP and 5500 rep; that is a massive amount. All the material you got from scrapping all your leveling gear will come in handy here and I imagine that you will be able to trade other players for different turn ins. I highly recommend trying your best to do all 11. Also, this will be a great opportunity to make some serious cash for your profession because people will be buying the same items in bulk.
Any decently geared 90 can complete a Pit of Saron trash mob run in 3-5 minutes. Each mob in the heroic version has a chance of dropping a Battered Hilt, which sell on the auction house for around 10k. Video guides will show the best route to take to pull all the trash mobs at once if you're a class with good AOE; other classes can simply pull less mobs at a time and loot as they go. While this method is a little less reliable than farming Vale-- after all, you're left to the mercy of RNG gods-- it has a higher chance of huge windfall because you could get a multiple hilts every run. Pull the mobs, burn 'em down, and cross your fingers when you loot. On top of the hilts, there's plenty of vendor trash, BoP epics for enchanters, and even a trinket that turns you into a gorilla. You will have to have completed the Forge of Souls in Icecrown Citadel to access this particular dungeon, though.
