Sordak, you to say that you was right. Even Paizo recognized that imbalance problem and made the 2e classes more balanced, in combat and outside of combat, since E2 din't released, i can't detail why. As for Vampire, the Masquarede, V5 changed a lot of things too. A lot of "blood sorcery" "powers" that could be used at will on V20, now require an ritual.
I still think that if you are adaptating an book into an movie, you need to be faithful. Same with manga, why Hellsing ultimate is more loved? Fullmetal alchemist brotherwood than normal fullmental? The best HP movies are exactly the last ones, more faithful to harry potter books. ToEE was very true to pnp rules and was amazing.
