Fixed hp
Fixed stats or point buy as the default, rolling as the undeniable "I hate my players" variant
Five person party as the default instead of 4
Official credence to the "wish list" method of determining treasure (I don't think there should be actual wish lists, but just pushing the idea of putting in loot useful to the PCs. Even if many 3E DMs like me did that, the offical rule was random table rolls.)
That's all I can think of right now. Basically, I just like the parts where they removed randomness from factors that have long-term impact on a character. The rest of the edition I hate.
