Why do you keep using this control scheme where we can only select one character at a time? It's so much clunkier than the RTS style control scheme almost every CRPG has used for the last two decades.
Why is this game's UI just one big unsorted hot bar? D&D has classes, and classes can have a wide variety of abilities and spells available at one time and then change them frequently. Dumping them all on a single hot bar and having the player manually sort and resort them sucks. These are issues CRPGs have had figured out for years, so why can't BG3 meet that standard?
