That’s not reasonable, That’s just stupid and you are trying to make it sound smart.
You're speaking from the point of person who already know what will come next in act 2 and 3. Try again because that’s just stupid and you are trying to make it sound smart.
Not trying to butt in or escalate but if there’s nothing resulting from that choice it’s unreasonable regardless of the players knowledge going into it. It’s also reasonable to assume most players would talk to the goblins, get said information, and then still defend the grove. First playthrough I did assume it would lead to a legitimate separate path and it never did. With my extremely limited forgotten realms knowledge I just assumed the absolute was some sort of evil diety at that point and not something you would have to fight.
