My personal bias is that builds around Protection Domain have now been severely weakened, and that the Domain itself is not worth taking. There are so many better options available now.- Greater Sanctuary and Protection Domain now share the same cooldown timer, using one will disable the usage of the other for 4 minutes.
- Protection Domain has its duration changed to 5 + Cha Mod rounds to be in line with other domain ability duration
- Sanctuary spell is disabled temporarily. Existing potions and scrolls will not do anything anymore.
Essentially, what it does now is give you 2 extra spells (Minor Globe of Invulnerablity, and Energy Buffer). Energy Buffer is still decent, especially with ESF in Abjuration. Globe really is kind of useless, if you ask me.
In addition to the spells, you get an extra Spell Slot with a Semi-Extended Upcast (DC) Greater Sanctuary. And that's it. It's very, very unfortunate that they share the same cooldown and are otherwise indistinguishable from one another.
This change is akin to slapping a cooldown on the War Domain's Battle Mastery after you cast Aura of Vitality.
At any rate, I hope the Protection Domain power will get some kind of buff, as it is nothing more than a Greater Sanctuary spell with a higher DC now.
But like I said in the beginning, I'm very biased. So let's discuss whether this was a good idea, a bad idea, a necessary change. What say you?
