Once you get to level 70, you will soon find that you want to be Revered or Exalted with a lot of factions. You'll need to be Revered to get your Heroic key for each set of instances, and it's likely that at least one faction will have a reputation item that you'll want to buy.
If you don't plan ahead, getting to Revered with Cenarion Expedition can mean a lot of Steam Vaults runs. If you want to avoid that, a little planning and patience will get you Revered with no trouble.
Ways of Earning Reputation
There are a number of ways to earn reputation with the Cenarion Expedition:
- Handing in Unidentified Plant Parts (Until Honored)
- Killing monsters in Slave Pens or Underbog (until Honored)
- Killing monsters in Steam Vaults (until Exalted)
