As I said, the author comes off as snobby. In fact, he contradicts himself multiple times (stating he doesn't look at the term negatively, yet using it in that light nonetheless), and yes, he highlights "painfully" obvious advice. I agree that a 7,000 (really?) word essay was not required to point this out, but we as a group DO need to address those "painfully" obvious problems as well. As for the calculating is for nerds etc. etc. If you do that, you have no life. Subjective as it may be (and untrue to a very large degree), the ones that take this to an extreme DO get annoying. I will admit, I do stat crunches from time to time when I play video games, but I won't insult people or make a big deal about small differences.
Also, the way by which the author highlighted the effects of newer players quitting on dedicated players was, while obvious to some, ignored by... well the ignorant.
/sigh... I guess this article/essay should be directed at the people that do exhibit the extreme behaviors so I'm not surprised it isn't well received. I had always felt the FF XI community was very helpful save the occasional oddballs who would ruin the experience for others. Let us give the author the benefit of the doubt and assume that he was targeting these players.
