With the blessing of sanctuary changes I am beginning to think they should just remove it and make the 21 point talent in prot make your BoK give you 3% damage reduction when cast on yourself (maybe everybody, don't know if that would be too OP for dps/heals in raids though) and self-only passive mana return on block/parry/dodge regardless of which blessing you have up.
also, with this gear talk, did anyone bring up the Reforging thing Blizz said they're going to add in the expansion? It sounds pretty awesome to me and a way to change gear like I always thought they should, so they can accomodate specs that have a pretty unique gear niche without having to add it to loot tables that the majority of players won't want.
I think it was in a panel discussion but MMO-Champion had it, and basically they said BS, Tailor, LW, JC and Engineering would all be able to "reforge" items based upon their profession and slots, and those items would then have stats changed/tweaked but it would lower another stat. So if it works the way I expect it will, then you could see things like a shaman taking some resto gear and reforging it so he gets hit rating for his elemental set, or a tank taking some dps gear and reforging it so he gets more stamina for less strength/agility or something.
