Larian should just have the backbone to let gen Z rage how unfair it is that they aren't revealed what they shouldn't know, because they know from YT there's a secret door. If you don't have the guts to keep secret or hidden things actually hidden, don't put them in the game to begin with.

So yes, I fully support the OP and don't personally want to know when there's something the party failed to notice. Because given that information, I WILL bring the entire team down there with Guidance one by one, because that's how the game is encouraging me to play i.e. cheat. And it doesn't feel great.

The game should use more passive skill checks in many cases. There are situations when it makes sense people with a high skill level always "got it" while people with zero skill and a negative modifier can't just luck it out. That said, Perception should be a bit random by nature, while Investigation and actively searching less so.
