I didn't find the article to be out-of-line negative or one-sided. It wasn't very well written, but she did make some good points I've been wondering myself.
I believe the article describes fairly well how people who aren't FF fans will feel when they try the game: they will see the some of the current MMO standard features implemented in a bit less user friendly manner. They may enjoy the beautiful world and the ability to play multiple classes on one character for a while, but soon they will begin to wonder what's in there that's worth of the monthly fee. What's the thing that sets ARR apart from other, free-to-play MMOs and WoW?
I can't answer this question. I feel we don't really know anything about what this game will be like, how is the playing experience like. This is not only because it hasn't been released yet and I haven't been able to try the final version, but also because we haven't received any information on the content or mechanics which might set this game apart from its competition. I know I'll be trying this game for sure, and I might even be staying for a while even if I hated it at the start. But that's me, a FF fangirl. Those players who don't have any emotional memories attached to the series might not be as patient.
People are in a full blown fan rage mode over her not knowing what's Bahamut and GW not inventing active time events. But those things don't really matter, as she wrote it just as the wider audience will see it when they'll try ARR for the first time.
Edit: It really comes down to this, as Ben Kuchera wrote:
So, other than being a FF title, why is the game special?Also, if you want to represent your game and get people interested, tell us about why you like it. Explain why you find the game special. Counter the arguments of the author of the article with your own experiences, or thoughts. That's the way to win people over, and to be good diplomats for a world you're obviously passionate about.
