Yeah, I am a little disappointed in Thaumaturge. It feels a bit weaker than Protector. I think it needs either another skill, or a bonus spell to make up for the Channel Divinity going to everyone.
LOVE the changes the Divine Intervention. That is reliable, powerful, and just great.
Not sure about Commune. It is fine, but meh.
I think Divine Spark is now way too weak. (will get into that in a moment)
Trickster's Magic is underwhelming I think, but also.... bonus action invisibility and bonus action Hypnotic Pattern are not bad spells. That is the entire list, which feels too small, but the few spells it works on are good. And in exchange for that AMAZING Invoke duplicity? I'll take it.

But.... I am utterly confused by one thing.
Why does Life Domain suck SO MUCH.
Divine Spark is a ranged 1d8+mod heal. Which is basically just a ranged cure wounds. Now, if you have disciple of life, then cure wounds is better, becoming 1d8+mod+3. However, as has been discussed many times before, the healing just isn't that good once you get past low levels. Disciple is interesting, but overall it is a drop in the bucket compared to what you need for healing.
Blessed Healer just gives that drop to the cleric as well. I mean, sure, I might regain 5 hp if I cast Aura of Vitality, but that's not exactly worth a 6th level ability.
And now Preserve Life can let you spend a channel divinity per spell level to cast an abjuration spell for free. And it starts becoming a bizzare dance. a touch 1d8+mod+3 is better than 1d8+mod at range sometimes, but it isn't better than 2d8+mod at 7th level (which is WAY too late) so you don't actually ever want to use Preserve Life to cast a 1st level healing spell, unless it is the bonus action Healing word? But every time you use Divine Spark to heal, you don't use Blessed Healer OR Disciple of Life, making them worthless. Now, maybe sanctuary or protection from good and evil could be good uses of it, but are those worth not having your extra healing?
And is there anything you could cast as a 4th level spell that is worth 16d8+20 healing NOT being used?
Like, I have a quibble or two with the other subclasses (Trickster's Magic being highly limited, being uncertain is Corona of Light is worth your action for disadvantage against damage spells alone) but the Life Domain just seems fundamentally broken, because it is constantly fighting itself.
And the other Channel Divinities?
Invoke Duplicity is superior to just about every Channel Divinity option in the base class.
Guided Strikes is a Reaction "you hit" and is way better than the divine Spark damage most of the time.
Radiance of the Dawn is better than the divine spark damage at every level, in every way.
But I just can't tell if a few extra casts of Sanctuary or Shield of Faith is actually that good for the Life Cleric.
