BoSanc will change in Wotlk

Anyone see the new blue post clarifying buffs and debuffs in Wrath of the Lich King?

Found an interesting categorization for Blessing of Sanctuary, regarding buffs that do not stack:

"Damage Reduction Percentage Buff: Grace, Blessing of Sanctuary"

Grace is a priest ability reduces a target's damage taken by 2% after a flash/greater heal lands. I guess we can expect a similar effect from casting BoSanc in Wrath.
