Mechanolord Capacitus drops the kickass
Thoriumweave Cloak in heroic as well as regular Mechanar, if you don't have that from regular mech.
Everything but the gloves of the
Wastewalker Armor set drops in heroics: Tunic in BF, Helm in Durnholde, Pants in MT, Shoulders in Auch Crypts. For DPS these are all right at the top of the list of blues.
Seems like we've covered just about all the heroics, eh? I myself have only run a few, but it's nice to know there's something worthwhile pretty much everywhere. Let's get to work!
