Some of these questions need to be retagged for sure, and apparently, such an initiative has started as old questions have had their tags swapped in the last few days. Two examples from the last hours are:
- Using 3d6 instead of d20 for D&D Next
- Was Murder in Baldur's Gate a part of the D&D Next/5e playtest?
To try to not overwhelm the main site with old questions and draw too much attention, we should stagger the re-tagging as needed, and possibly communicate which questions do or don't need attention further in this process.
Which of the questions demand immediate attention and which might need to stay 5e only?
[For the record: we're down to about 18 on 2022-09-10]
D&D 5e was officially published in or around July/August 2014, so the cutoff date for easy sorting is, that most items asked before are most likely playtest material.
It might be possible that a considerable amount of more than 100 questions asked before July. About 30-ish of that might need the Next Playtest tag but had it swapped in the renaming to 5e - which would need to be reversed.
