Earthwarden is a great weapon and a must-have for every level 70 feral druid who tanks in bear form at all. The price is a steal for what you get; the hard part is grinding the reputation for it. However, it's really not that bad. Steamvaults can be a very quick and very easy dungeon with a good group and on certain days I've done it 3 times in a row in slightly less than 3 hours total for all the runs. It took me approximately ~30 runs to get from honored to exalted, which isn't bad at all compared to previous rep grinds. (Argent Dawn, anyone?) It actually took me more runs to get my Moonglade Shoulders!
