IMHO every campaign like this feels like Monty Python and the Holy Grail: The DM tries everything to keep the party on the right track.

I have a secret guys : the bard is not a bard. It's a rogue with a bit of charisma and a music instrument proficiency!
In my last campaign my bard could out rogue our rogue. I tried to be chill about it and let the rogue do rogue things, since my character really made her character kind of obsolete outside of stabbing things.
I want a bard that is basically one of the two dudes from Kung Fu Hustle with the lap harp thing. Firing off invisible knife missiles from the harp.
This is why I prefer PbtA systems: I experience genuine joy whenever the PCs break my stuff.
Definitely need those improv skills though!
Boi, been there!
I spent quite a lot of time at university doing improv, and what I learned has come in useful in all walks of life, but also for roleplaying games. It doesn't matter whether your improvisation and storytelling skills are good or bad, everyone improves with practice and experience.
My players are starting a religion, with them as the centerpiece, could have expected it.
I kinda get what you are saying, but... for me improv is a skill that is hard to train or to master and relies a lot on luck. Will I think of something cool now and then ? Will I get ideas ? How will my brain interact with this exploration ? Its hard to say that improvisation isnt highly reliable on what you get at that moment between neurones.
How many times have I thought of better, cooler or more adapted ways to do what I had to improv days or weeks later ? Time is a finite resource, and when improvising time is your enemy. The longer or shorter you have to think, the better or worse it might end up with.
