Okay now everyone be quiet because I, That One Guy That Doesn't Play WoW, will talk now.
This was a great article. It reminds me of that one Final Fantasy game in which, due to a bug, the Magic Defense stat did nothing, since what it should do was wrongly tied to the regular Defense stat. I think it took players a few years to figure it out, it may or may not have been when they looked at the source code.
On one way, it has to do with the 'social contract' of gaming that other article was talking about. We expect Attack to mean that you hit harder and Defense to mean that you're not hit as hard. If it means something else, what's the point? Luck is troublesome because there's nothing that leaps to a player's mind when he thinks of it, since each game has its own spin on it.
This also reminds me of Bartle's discrimination of the four player archetypes - Explorer/Spades, who tries to find new stuff to do, Achiever/Diamonds, who tries to be the best, Killer/Clubs, who enjoys conflict with other players the most, and Socialer/Hearts, who enjoy story, roleplay and companionship. It makes me think that there might be 'super' versions of these archetypes. Every test of this kind I took pegs me as an Explorer, and it fits the way I play, but if I can't solve a puzzle I'll look up the solution. However, a Super-Explorer is the guy who reverse-engineers the game to figure out what makes it tick, and the Super-Achiever will need to look at the Super-Explorer's data to figure out how to be the absolute best. The problem with WoW, as inferred from this article, is that the data is so impenetrable only the Super-Explorers can unveil it, and since all the Achievers are fighting against each other to be the best, they all need to have the same data to be the best and can't (well, won't) figure it out on their own.
Compare it with Magic: The Gathering, where the rules for each card are literally written on it, allowing rogue decks to make a sweep in tournaments. From this article I doubt a 'rogue setup' could be suddenly found in WoW to make a certain boss raid much easier.
Okay, not sure where I'm going with that. You can continue to argue now, children.
