I made myself a full set (5 bags) of this and tried using it. As an Enchanter. I was on permanent exhaustion. So I gave them away. I was sure to inform others of who should or should not be using these. Seems Tanky to me. I decided against their use entirely and instead opted for a single Goblin Chief satchel. But i made some tanks pretty happy. And strongly advised against their use for int casters. And advised Shammys/clerics to restrict it to one.
