From the patch notes:
Blessing of Sanctuary: This blessing now also increases stamina by 10%. This effect is not cumulative with Blessing of Kings.
This fixes nothing. We still have to pick between sanctuary and kings. 10% stamina is nice, but we're missing the 10% strength and agility. Those are not insignificant, especially the strength since we have so much on gear. When block gets fixed I don't think we're going to be happy about having to pick between 10% strength and more regen.
Sanctuary should not replace kings. Make it a passive ability of 3% reduction and regen tied to something else, like devotion aura or righteous fury. It's fine as a talent, it's not fine as a blessing.
Upon slightly later consideration, I'm less annoyed. It's a definite buff to soloing or any groups without other paladins. I'm glad Blizzard is trying to fix it, I just wish they weren't going about it the wrong way.
