Wow Powerleveling-Trial of the Champion
Paladins will want to start off with Greaves of the Grand Paladin and Helm of the Bested Gallant. There"s not a whole lot of selection from either normal or heroic mode. Once you"re done farming in there, look into acquiring Gauntlets of Revelation and wow powerleveling of the Argent Armistice. That"ll cover the feet, helm, gloves and leg pieces respectively.
Druids will want to pick up Gloves of Dismal Fortune and Leggings of the Snowy Bramble from the heroic. Run normal mode to replace the blues. Check out wow powerleveling of the Somber Keeper, Mantle of Gnarled Overgrowth, and Binding of the Tranquil Glade.
Shamans, like Paladins, are also limited. Out of normal wow powerleveling, the Carapace of Grim Visions is a solid pickup for any Resto Shaman while Leggings of the Bloodless Knight can serve in either capacity for Resto or Elemental Shamans. Lastly, if you need a decent belt, wow powerleveling of the Dauntless Conqueror comes from the heroic.
