Well, it is not like devs should jump as soon as any fan says them to. There may be some technical difficulties with it, or ammount of work does not make it worth, or may be diffirent fans make completely opposite requests. They take our suggestions and complains into consideration, but they filter them through their own perception.
Why don't they listen to fans all the time, and don't try to fulfill all of their wishes? Probably bec. it is impossible to please everyone (people want completely opposite things), and Larian devs are smart and confident in their vision of the game. As they should be. PB listened to much while making Risen and we all know how it turned out.
