When it comes to controller support I'm playing on Stadia and use the controller sometimes. Don't see any problems when i go back to mouse and keyboard.
Are you sure you are in the right thread? Because this isn't about controller support. It's about how shitty the default control scheme is compared to other titles in the genre.
Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
