Honestly, I really really really hope they change their minds about companions. It was the one thing I loathed in DOS2, them all dying cause they were not in my party at an arbitrary moment. And it'd be even worse with the party limit of 4 and if we do not get non-origin companions (which I really hope we do get non-origin companions that are not just the merc system of DOS2). The not being able to return to Acts thing I would be fine with except it goes against the design of BG cause the previous ones you could return to many locations or even use a location as your hub, so I hope in this one you will be allowed to return to past locations and travel through areas.
