There are problems with the two existing system tags:
- dnd-next may or may not be the name of the later edition.
- dnd-5e also may or may not be the name of the later edition.
- Both refer to a system that doesn't exist yet, therefore the current questions are about rules that may or may not actually be in a game system of that name in the future.
I propose that we create a dnd-next-playtest tag to cover these questions. It is:
- Accurate and future-proof: It accurately reflects the name of the system currently being asked about, and will keep these questions and answers segregated from future questions about the next edition of D&D without having to clean up the tags later.
- Discoverable: It will be mostly discoverable as the asker types in a tag. Anyone typing in "playtest" will also have the chance to notice that we have a dedicated D&D Next playtest tag. It won't intercept people who are tagging dnd-5e and avoiding the "Next" name entirely, but those questions also appear to be a minority (1, as of this typing).
That should resolve the problems with the existing tags. Manual retagging should be enough to handle incoming questions. A dnd-5e-playtest synonym to dnd-next-playtest would nicely close the discoverability gap mentioned above. We might consider a temporary synonym from dnd-next to dnd-next-playtest (to be removed once/if "D&D Next" ever refers to a non-playtest ruleset), but only if manual retagging proves to be troublesome.
(To forestall one objection, we can't synonym dnd-5e to dnd-next-playtest or any other proposed tag because we have existing questions about "D&D 5e" from before Next was announced. (And I'll leave aside the question of whether we should have speculative dnd-5e questions as a can of worms that's best considered separately from this issue.))
I propose that we synonym dnd-next and dnd-5e for now, and make sure that all current posts are ALSO tagged playtest. After all: if this works then D&D isn't likely to be the only game that will go through a public playtesting period such as this nor the only one that will have significant changes when playtesting happens. This way, when the next game down the line starts playtesting we can tag it with nextgamedowntheline and playtest.
This would make it obvious that these questions were asked during the playtest period, while not over-cluttering the tagspace with extra nextgamedowntheline-playtest tags.
