Toned knows his stuff but just wanted to add Mana Tombs Heroic is brain dead easy for 5 shamans (no kiting required). That's 4 easy badges in 45 min or so (yes 4 if you do the chain quest to open up the forth boss Yor).

Edit: Add first boss Mgt to that list, easy badge and epic (and a nice caster dagger that drops too - 15 min run or so).
