Further evidence of this can be found in this thread at story-games, which shows that people over there "get it" to a much greater degree than the herd at rpg.net. Here's a paragraph that bears quoting:
Also, about wanting to play a fighter and not getting a good Strength score... I know that my thinking's not that useful for most, as I don't exactly run D&D by the book, but why not just play a weak fighter? If I did the thing with ability minimums for class entrance (which I currently sort of do; some classes require a successful ability check, which is similar), I'd ensure that I also have a set of class options that have no minimums, and from which players could develop their characters into whatever they want them to be. So make that low-Strength guy a fighter, experience the suckyness and then fight your way out of it. From zero to hero, I say!
Couldn't have put it better myself. The obsession with optimization so prevalent on web forums is something that never fails to boggle my mind, not because it's couched in whiny and entitled terms (although it sometimes is) but because it's so godawfully boring.
