There are some things I like about One DnD, like moving stat bonuses from races to backgrounds. It opens up a lot of interesting RP possibilities and moves away from generalizing all members of a race as being some kind of eugenics-based stereotype. It's not the 1930s anymore, fantasy worldbuilders. But I'm not keen about what they are doing with Inspiration. It should really be just a Bard thing. I don't want all the players to be frequently using Inspirations and gaining them back again or passing them around. In a game that has a lot of mental load, Inspiration often feels superfluous and cheesy.

I feel like the Bard's reaction Inspiration is going to work like this:
DM: The door is locked.
Rogue: I'm going to pick it. *rolls a 8*
DM: This is a surprisingly intricate lock, you're not picking it.
Bard: I'm going to whisper something inspiring in the rogue's ear as they pick the lock. You got this buddy! *rolls a 6 to add to the rogue's 8*
DM: Your roll is now 14, and you've succeeded in picking the lock.
