These new quests include things like disciplining 20 dragon-maw peons

Do these new quests until you reach honored reputation? Now you will have more quests available to you (starting to see a pattern yet?). It means you have a chance to gain more WoW currency (copper, silver and star trek online credits).

Your combat pet will be upgraded so that you can summon a combat pet in all zones. These new quests include things like gathering materials to build a cannon, killing a number of mobs in Twilight Ridge in Nagrand, and participate in a race where things are thrown at you to make you lose.

At revered reputation, you will be able to get another daily quest where you get to lead a battle. You will also receive another upgrade to your trinket that adds 45 stamina.

When you get your reputation with Nether-wing to friendly, you will have more quests available. The majority of these will be daily also. You can also continue the earlier repeatable quests. These new quests include things like disciplining 20 dragon-maw peons, collecting cargo from a mine, and killing a number of certain mobs.

Repeat until you become exalted, at which time you will be discovered as a spy (by no less than Illidan himself), saved by your merc friend, and given your nether-drake as a quest reward.
