And I challenge it with my own experience and the underlying notion that the game, being a social atmosphere, has no need for isolated calculation immediately before, during, or outside of combat. 4E eliminates the extended impact of vaguely named bonuses that danced through a Caster's spells-per-day listing that we had in 3E: What is "Divine Power", really? +6 to Strength bonus isn't discretely anything Divine or Powerful. Is Cat's Grace a term of physical attributes or psycho-cultural? Instead, we have Stunned, which is agreeably Stunned and only Stunned in a method different from Dazed, Slowed, and Prone.
Simplified math and phraseology is a virtue of a clean and robust system, and my group uses 4E in lieu of other D&D-likes because of this.
