Blood Guard Shaman Set Bonus Not Working

[Psyshadow]

Describe the bug
When swapping the blood guard helm (with the rest of the set equipped) for enhance shaman, to the Helm of Exile, my attack power goes down on the sim even though in-game it actually goes up.

To Reproduce
Steps to reproduce the behavior:

1. Equip full blood guard set, note AP
2. Swap helm to helm of exile, note AP goes down - in game it goes up.

Expected behavior
In-SIM AP should = in game
