One thing that really pisses me off about the FFXI community is that what seems like a vast majority (or at least a large percentage) of the people who play this game absolutely refuse to acknowledge any short comings with FFXI's UI or discuss topics about ways to improve the UI.
If you want to discuss any other topic at all, or suggest improvements to any other area of the game, the community is usually willing to do so in a perfectly mature and respectful manner. But as soon as the subject of UI is brought up, the community instantly degenerates into one of the most immature group of children I've ever encountered in any MMO, slinging insults and flames far worse than anything I've ever encountered in WoW /trade chat.
Why is this? Why so defensive about the UI? FFXI's UI is not some holy grail. It is not some almighty pinical of perfection. In fact, it's horribly flawed in many, many ways. The fact that there are so many windower plugins and various third party programs that all try to fix FFXI's UI is irrefutable proof of this.
Yet despite this, a good chunk of the FFXI community seems totally incapable of discussing UI improvements with any degree of respect or maturity.
FFXI players claim that this game has one of the most mature communities in any MMO, but from what I've seen the level of maturity is exactly the same as any other online game.
