Okay, the things I'm thinking about are the 226 stam trinket and the cloak. Right now I have the platinum mesh cloak and I'd be replacing a 113 dodge + 4104 HP trinket if I bought the Skeleton Key. I suppose there's always the set pieces and the 264 non-set pieces. But I'll only get those if told they they're a way bigger upgrade.
Here's my armory for clarification: http://www.wowarmory.com/character-s...ivh&cn=Varhgon
Dammit, I'm in ret gear on the armory.
