It depends on the viability of the suggestion/request and the hours already spent in development.
They already have addressed almost all the issues the regulars had. We (As Sameer pointed out) have been posting tirelessly for the inclusion of classic mechanics, gameplay and narrative and they have delivered.
As for issues of legality....I believe that posting an idea in a forum makes it officially yours.....I think Jazz can elaborate on this. Of course the thing with ideas is that everyone has them...the Dev team probably had a truckload of purely awesome ideas but could not implement them.
At this point...all we can do is provide actionable feedback. Things which are reasonable and have a chance of being implemented. "Bring back Ironside" "Retire Sam" and all such feedback will be ignored as it is far too late in the development stage for them to change anything
Besides THEY are making the game..they have majority say in how they make it.
Keep posting though...you never know.
