In fact I bet the ones who are always talking about numbers and values are the minority of online gamers. The majority don't care about statistics to that degree.
They are. Thats true in almost every game. The only real exception is games that are designed to be massive number crunching exercises anyway, because those only draw in the type of people likely to post on forums.
The thing to remember is that the forum posters don't form an accurate view of the entire player base. People who post on the forums a lot skew more towards the technically savvy, the hardcore, and the theorycrafting inclined.
MMO forums are the best example of this. Blizzard routinely ignores what the players say they want on the official forums, because the players on the official forums mostly represent hardcore raiders, hardcore PvPers, and not the more casual folks. Unfortunately the casual folks represent the vast majority of the actual set of paying customers.
Another MMO tried to cater to the forum posters. They listened to people whose feedback was based on nostalgia-tinted views of the "good old days" of Everquest, and how WoW ruined the genre by being too "noob friendly." Based on that feedback, we got Vanguard, which was probably the biggest failure in MMO history because it appealed to absolutely nobody outside of the whiniest forum posters.
By all means, they should listen to people who post here. The forum community tends to have a lot of dedicated players who can do analysis and come up with good information. But they can't listen to this group exclusively. This group doesn't represent what the majority wants, and it doesn't represent a group big enough to make a game successful. The game experience of the people who only play single player, or play multiplayer with their friends on a LAN against a computer team matters too, but those viewpoints get totally ignored in the doom and gloom about how "race X can't possibly win!"
