Personally I think the immediate answer I want to give is yes. It makes sense that a dev team should engage actively with the community. Simply put, a player base will always be able to find and recreate bugs, obvious balance needs, and interactions before any dev team. So being an active part in the community should mean the dev team can make changes that will effect the quality of life of the game.
On a deeper thought I remember that everyone has an opinion, and when a dev team starts bending their idea to the community it can move away from the original idea of the game. Considering how everyone has an input, I could see it being tough to implement them all within the parameters of the game.
