I never really understood the devotion towards core only. People stated their devotion to it in 3E, but always for the wrong reasons. People said core only was more balanced, when the opposite was true. What core only 3E did accomplish was a less untidy game easier for the Dm to control, not something more balanced.
You do realize that balance doesn't equate to the most important thing for every player of D&D. Perhaps it's moreso having a finite set of rules and reference books that everyone can in fact get a handle on and mastery of... that makes core appealing.
