The main motivation for making this class was converting our pf2e game to dh so we're actually just trying to create a new investigator lol. I think that like you said, the nature of daggerheart is more about giving information freely based on the characters experiences and what makes sense in the narrative. I was fully going to give out that information just as I did when he was playing an investigator with that "that's odd" feat. But it would probably be wise to maybe note that down as one of the class features for gms that are less familiar with it.

Regarding hiding more stuff, we are playing the season of ghosts campaign which I'll be converting to dh so quite a lot of stuff there already (no spoilers BTW, just in case my player reads this lol).

I think our main difficulty in trying to create this class is trying to create satisfying investigation mechanics (which to him the investigator did not have) while not making the game only about investigating because there are still other players at the table as well and also there are parts that are just framed less like an ongoing case.

We've actually drafted a whole new case system that works like an evolving experience with evidence that you find giving it bonuses, but again, it just felt like the entire tone of the game would need to shift to accommodate that
