Definitely should be heirloom.
I'd like to know more about the player-made armor/weapons and anything about new tradeskill recipes. I've had no luck finding that stuff yet. I do some some people looking to buy Ethermere Essence for as much as 400kpp each so they must know something I don't know about the use of such a new tradeskill item.
CHECK it out but still not better AC wise or hp per say then the feasts or brew
