As mentioned in the previous parts of this article, the players are usually unhappy with any changes, unless of course, the change simplifies things or makes things easier to do. But whenever the change requires them to change their strategies, there is widespread complaint, cries that the developers don't listen and want to ruin the game, threats to leave the game and so on. The mere announcement of future changes makes them very nervous, and they usually don't bother to read the full announcement, but rather immediately jump to [wrong] conclusions. There are, of course, some players that do like changes, and there are some players that don't care. But the bulk of the replies to any "future change announcement" is usually "Omg omg teh devs want to ruin teh game!11!!". Often times we just gave up modifying some stuff that we believed would be good for the game, but the players cried about it.
While the players usually play the game more than we do, most of them only care for their best interest. It is up to an objective 3rd-party to carefully examine the implications of any game system modification. That 3rd party is us, the developers, who unlike what some players think, want only the best for the game. It takes someone with a global vision of the entire project to decide what would make the game better for everyone.
A while ago, I was reading an article written by some web-based MMORPG developer who was dealing with similar issues. I can't find the URL to that article (I did try to google for some keywords, with no success). Basically what the author said was that after a while they just ignored the complaints and went forward with the implementation of those changes. And with time, the players actually liked those changes, despite of their initial overreaction. Reading that article was very informative and encouraging to me, so I vowed to do things in a different way from now on.
