Context in 4e is like crying in baseball. There's none of the former in the latter.
4e is a cold mathematical formula without context, subtext, or rhetoric! It achieves a high level of fun, y, by plugging in the ruleset, x, reliably and repeatedly with no variation and no emotion! The Maths are Perfect! The Maths are Sublime! The Maths will take us away to a happy field where there are no gnomes!
But....that's what the Maths say! We must listen to the Maths. They cannot be wrong. They are computers of fun!
Sorry, got a little out of control there for a moment. I certainly don't think that that's what 4e means to imply, but I won't dispute that you have come to this conclusion, specifically because of the existence of paragraphs like that, which say "We know what's fun for you!" I'm willing to chalk it up to poor writing and misplaced confidence more than deliberate malicious intent to tell you you're having badwrongfun, though.
