I don't know if you are aware of this, but for legal reasons, once you have posted your suggestions for the continuation of the story you made sure Larian will not take them into consideration, even in case they look similar to what they already had in mind they would now be looking for ways to prove in court they didn't rely on your ideas, but thought of them earlier. Otherwise you'd have reason to sue them for royalties. That is why authors (especially ones who plan to write sequels) never read fanfictions of their own work, so they'd have deniability if what they write turns up to have similarity to what a fan wrote.
