No, this isn't about political correctness or racism. It does, however, run along similar veins. No, this doesn't have anything to do with StarCraft II. It does, however, have its roots in World of WarCraft.
I very often get into debates with other players concerning the feasibility of various actions or specializations in the competitive parts of the game. The other players often insist on a specific set of conditions and actions no matter what the situation might be. After bumping heads numerous times, I finally had an epiphany of sorts as to the nature of the issue.
It's a matter of simplicity.
How it manifests is more complicated, but it boils down to the inherent need to simplify matters. I will probably not be able to appreciate or understand art on the same level as my sister, and as such must suffice with a simplified and more base appreciation of a painter's work. My mother will never be as capable as my father in the fields of mathematics, and as such will simplify her understanding of extremely advanced concepts. It's a simply human method of coping with the fact that there is more information and activity in the world than we can ever learn and know.
Often, this part of human nature is abused. A fundamental assumption of our simplifications is forgotten. Specifically, that the simplifications are just simplifications and must be recomplicated when appropriate. It's implicit in the act of simplifying or generalizing that upon leaving the realms of the general for the specific we mustn't rely on the simple or general. Failing to do so brings about racism and other nasty things.
Now that I've bored you with that, here's what happened next.
One of the players I was discussing this with scoffed at the idea that this build had any viability in fighting other players whatsoever. He insisted on one specific ability as paramount and absolutely necessary, claiming it was impossible for anyone to fight other players without it. After a few amusing jests on my part ("You can fight other players without even swinging a sword! You'll lose... but it's still a fight!") I positted the following.
If all other players have specialized in a specific way, why not specialize in such a way as to be spefically devastating to people with the "cookie cutter" specialization? They won't know how to fight you (as you're the only person who plays this way and as such very few players will have encountered your style) and you'll know how to fight them (as every other player fights the same way). My argument, to be brief, fell on deaf ears. The player continually insisted that there was only one way to do things, and that doing things any other way was pointless.
Thinking on this birthed the epiphany. When attempting to understand a complicated situation involving 9 different "classes" of players each of which has varying degrees of ability in specific roles such as "damage", "healing", "control", "surivival" and "support" for which players can specialize to maximize specific subsets of each, one immediately wants to simplify matters as much as possible. Attempting to account for each individual player's inherent abilities alongside how they've specialized and fit each player into your battle squad like puzzle pieces is a daunting task. For the average person, this is simply too much to ask. They're forced to simplify.
To simplify, they typecast the 9 "classes" into specific roles to which they have the greatest ability. It's a lot easier to remove three or four other assets from a class and boil them down into one or two than to attempt to account for the five I mentioned. It's simple, X number of people are "damage dealers", Y are "healers", Z are "controllers" etc. One person can now easily account for exactly what each person is supposed to be doing and easily judge them accordingly.
While a useful generalization, it is too often forgotten that one should "recomplicate" matters during an in-depth discussion. This is compounded by the tendancy of devoted players to assume that, due to the time they've invested in the game, they are knowledgable about it. To an extent this is true, but to another extent it isn't. I could potentially spend the rest of my life visiting art galleries and examining paintings, but there is a limit on how much one can passively increase their depth of knowledge. Without active attempts to plum the mysteries of the works, I'll end my life barely more knowledgable about art than when I began my pilgrimage.
The result of all this is a lot of people bringing simplified visions of matters into in depth discussions. In normal conversations, say my sister and a friend discussing some work of Monet, neophytes such as myself have the common decency to avoid barging in with opinionated and uninformed sentiments. This is possible because we immediately recognize our ignorance. When everyone makes a fundamental assumption that they are an expert (or worse, a greater expert than others) very little understanding results from the discussion.
The simplification marginalizes any number of important possibilities. For example, if I ask, "Is it ever wise to enter a dark alleyway?" the obvious answer is "No! That's dangerous!" However, it ignores any number of possible situations. What if I'm walking a dog and it runs down the alley? What if there's a runaway car plowing down the sidewalk? What if I see someone in need of assistance? These situations may or may not be common, but in the name of simplification they are forgotten.
Again returning to competitive video gaming, the simplifications allow average people to work together well. However, they will never be optimal for "pro" players. The near infinite diveristy of situations calls for a nearly infinite adaptability, something the simplifications don't provide. There are numerous possible situations which can call upon someone in one role to fill another. Though not their express mission, they may be the only one able to address a sudden issue or development. Requiring them to ignore this if it is of greater detriment for them to do is ridiculous. The most excellent of "teams" will be those that act as a web, not only filling their "best" role but also the others. Such a force would easily steamroll any "simplified" opponent.
Sadly, people such as I who recognize this often find ourselves filling in too many roles simultaneously upon joining battle with a randomized group of people. Very few people are able to see beyond a single role, and so very often many important things go undone.
Perhaps eventually I'll meet a group of people who all see what I see.
