I'm saying, you can go back to something closer to how things once had been presented.Like, what? What are you arguing for, or against? I'm just not following your thought train.
You can do this with rules, by reintroducing mechanics that previously existed.
You can do this with lore, by overwriting previous retcons, or by implementing retcons for changes not well received.
I personally am not saying either of these need to happen, because realistically neither of them will happen so its a moot point. 5e is far too successful in any number of ways for them to even consider a 4e -> 5e shift. There is simply no need to do so.
They could though.
