I have read people mention that it's odd, that you are friends with a god but cannot ask him for help. So it is nice that they added it. I doubt it will help both of them much though, because when you play as God Gale, the narration tells you that Gale isn't just free to just help his old buddies. They have to be willing to pray for his favour. So I am curious how the scene plays out. I am sure, yt will provide.
What the patch notes didn't mention, unless I missed it, is that Avatar Spawn Astarion now has a new ending option - with romanced human Gale at least - to move to the Underdark together to help the other spawn. Even the party dialogue was slightly adapted so that it sounds like they are both working together in keeping the spawn save. It has all the "together we can do everything" energy that romanced Spawn Astarion's ending never quite manages. I am really happy about it. (As I have mentioned in two other threads, so I will now shut up about it. )
