If you listen to the community all you get is "more content = more better". It doesn't matter if it's a good idea or not, community polls will always result in that you add it. After that you'll get the @#$%ing in the forums about how unfun the mechanic is. You have to check if it fits your gameplay concept. If it doesn't you shouldn't implement it. If you let the community decide about gameplay related stuff you get a messed up game.
