I'm beginning to think it was a poor choice of words to describe the tiers of play as basic, standard, and advanced. I understand why they picked basic and advanced, they have some nostalgia creed with the most established players. But they also bring with them some unwanted baggage that hinders discussion and even communication, not to mention confusion.(And it distracts from the discussion of the standard game as a standard)
Just one example, I've seen more than one poster in enworld and the playground consider phb=advanced, ergo the phb must be 60% optional and full of modules and everything not in basic is strictly optional. (Truth, phb = standard, and while you can decide in your own table game to deliberately ban 60% of it, the purpose is you use it mostly as a unit and it contains nothing that wildly changes gameplay.)
I think this is one case were a less retro approach would have flown better. Or if they really needed to use advanced and basic, name and advertise advanced as standard and name what is now advanced something else (expanded? evolved?)
