After experiencing bg3 with WASD Character Movement and Native Camera Tweaks Mods I literally cannot play the game without anymore. The joy of just walking and looking around in the city! The pain of climbing stairs gone! These would be very welcome options in the base game.
As for the mess of using mods some kind of official/stable mod support and mod manager would be nice (as juggling around with dlls isn't ideal). How about including a list of selected/popular mods in the QA process before releases even? Not sure how feasible this is.
