This EA haves many problems, but lack of possibilities and outcomes isn't one of them. Not to mentioned when compared it to most of other RPG games or even recent titles.
Most arguments raised from "players" here are either players complains about not having whole backstory for the quest (like with 'Devil Hunt" and paladins or Rath) when no effort to do so was made and others are just obvious bugs and scripts not working which needs fixing.
Same goes for solutions were most of them sooner or later contradict themselves too limit player options and wanting more player options, so it ends up as personal opinion and not so much solution at all. Like companions when at the moment in EA(and it was mentioned few times by both Larian and Swen) we have like 3 Neutral (Gale, Shadowheart and Wyll) and 2 "Evil" (Astarion and Lae'zel) as theirs staring (key word here) characteristic and players are angry that there aren't and "good guys" and they treat player badly. Maybe it isn't emphasis enough in the tutorial, but theirs attitude matches beginning of this story. Where it isn't standard/normally established party with common enemy or higher moral goal, but just bunch of random people joined together by force- so using other to survive makes sense.
Even whole Astarion meeting right now isn't that bad. In coop it's just right at the moment even, your friend pretty much can just wait and see what happens or just shoot/backstab him when he holds dagger on you. In single player it's bit worse, but still you have attack option in most of dialogues and same goes for this one. Would adding some extra line make it better? Yes. Would it be game changer and have huge impact on narration, story and enjoyment of the game? Definitely no.
When your points aren't inherently wrong and some are valid they just seem premature (like companions and some quests) or lacking somewhat understanding how video games work. I encourage you here to pretty much go over other overall claimed as good story games or just your personal nostalgic ones. Then you will see how much games are behind compared to other media like books or movies and still require years of improvements in aspects like this.
