It's simple really. If we have 4000 people playing and 400-600 complaining, what do we call the second group? A vocal minority
Should the devs do as they say just because they cared enough to leave feedback? Absolutely not.
Does that mean they are at all times wrong and should be ignored? Also not.
The feedback doesn't have to be treated in a black&white manner. Feedback, along with other data that TW actually gathers(and we know that for a fact), can be used to draw conclusions - very carefully - before implementing them.
Oftentimes what the players feel is the problem is not necessarily the problem, simply because people can be wrong and it's up to the developer to use the available data and feedback to come up with solutions. Sometimes they can be exactly what the players suggest and sometimes it can be the opposite or something else.
