This is a lot of stuff that does sound cool, but I think it's for the best some of this was cut.

5. I think given he was a late addition, cutting the extra druid Grove stuff involving him was smart. After all, how would druids even know to get here in time since they're back in their Grove? Having deep druid Grove stuff in act 3 would have probably felt muddled and tacked on anyway.

6.Considering you can pretty easily find like, 3 soul coins alone in act 1, using soul coins to get out of the tadpole might have felt too easy. Plus I personally feel like making him a merchant would diminish him.

7. The game already has enough going on in it that a whole extra plane to explore would have easily felt like too much and a big tangent.

8. I think the Tav Urge thing could have been good, but I feel like without the sort of framing/prep of being told that the dark urge was a thing by choosing them as an origin, it would have felt off. Especially since unlike the original game, we are given absolutely zero context for Tav's prior life. So I don't think the urge stuff would have really felt right most of the time. Plus we hardly saw any of that I EA so it likely wasn't kept around for long.

19. I personally never felt like Daisy worked. And she certainly wouldn't have worked as a dream companion most characters would choose to leave the world behind for. She never felt trustworthy or intimate or like she actually cared about us, not at all like a potential long term partner. Her manipulations felt so overt and transparent. I prefer the guardian and think ultimately the Daisy change was a mercenary evil as she wouldn't have worked for what they wanted.

26. I think there shouldn't have been a Mol and Raphael plot line at all and this is exactly the sort of thing that should be cut for time. Raphael talking about claiming Mol's soul is the type of thing that should exist as a single interaction to give him a bit of menace and flavor but doesn't need to be developed beyond that.

27. There are too many gods as it is in this story. It clear didn't need the Raven Queen making things even more complex for no real reason.

Sometimes cut content gets cut for a good reason and the final result is better for it.
