SAB infusion in PvP
Anet says no.
Surrender and serve me in life, or die and slave for me in death.
It’s not a “bug” — it’s the result of PvP relying on the PvP amulet etc; in effect, the game doesn’t know about any of your gear (with a minor exception that some of the pieces have to be equipped).
To recognize the infusion (or auras from other sources), ANet would have to update the wardrobe to include this bit of cosmetology. So I’m not holding my breath that this would happen outside of an expansion (you might not have to purchase the expac to enjoy the change; it’s just so big that it’s unlikely to happen in the context of a smaller update).
