What I'd like much better: take advantage of the approval mechanic. The way you are going to play is influencing how the origins see you. Some will agree with you actions and some will disagree. If approval goes down or you do certain unexcusable things they will either leave or outright fight you. Let us keep them and let our player descisions be the factor that lets them stay or leave.
Something like that is already in the game. The problem is that not enough meaningful things happen for you to feel it. The only time you will notice it for sure is if you side with the goblins.
Regarding the getting rid of the party by the end of act 1 - yeah silly decision
