But that's a given - it's the obvious flaw of the system. As long as you know that, you will be prone (if you're intelligent enough) to filtration and perhaps even *gasp* actually seeing some things for yourself. For example, if I read that someone was talking about Inferno being FS3, I'd come to check it out, and after seeing what it was, I'd figure that entry on the Wiki to be completely and utterly false.
Of COURSE there are drawbacks to this system, but again, there are also drawbacks to the other system as well. You take the good with the bad. For me, the benefits outweigh the cons and the benefits of the opposing system. That may not be the case for others, but again, it's opinion and taste.
Especially when we consider stuff like this:
http://wiki.ffxiclopedia.org/index.php/Main_PageThe entire game's information is stored there. All I've tested and followed was 95% true, and it cut a HELL of a lot of time, what with its 12 000 articles. Yes, there were inaccuracies. Of course, it isn't pefect. So for example, while I was doing one mission, I followed it, got to a point where the info was valid, then got stuck, asked ingame, found out some things were updated in the last patch, then I acted accordingly ingame, deleted the outdated entry and put the new correct pathway to achieving the mission. I doubt I'd find that, or the ability to rectify a possible inaccuracy in Britannica.
We all know the default. Arguing further pro or against is just simply subjective.
