So, I'm loving Sekiro (A LOT). That said, I desperately wish combat arts could be swapped without pausing the game. I think the gameplay variety suffers greatly due to the current swapping system. There's no real purpose - its not like you can only change them at idols. You can switch whenever, but to do so you have to enter two menus. Who wants to interrupt gameplay by entering two menus? But also, who wants to use the same combat art over, and over, and over again? In short, I wish we could swap combat arts with a dedicated button, just as we can with prosthetic tools. It would add so much more variety to the gameplay, as you could experiment with different tactics without stopping the flow of the game. Is it possible to mod this into the game? To dedicate a button (perhaps the d-pad's down button) to swapping combat arts without pausing the game?
