The question Have the D&D 5E designers ever done an official commentary about why they have designed certain rules the way they did? was recently closed due to lack of focus (the close reason I chose) and designer reasoning being off-topic. I don't pretend to know the asker's intent, but I believe a similar question could be asked, while remaining on-topic. On to the example questions...
How has True Strike evolved from its first appearance in 5e to today?
The cantrip true strike is considered weak by well-respected build guides, such as Treantmonk's Guide to Wizards 5e. I am curious how (or if) the cantrip changed from the earliest D&D Next playtest to today. I'm interested in any errata (silent or otherwise) as well as its addition/removal from (sub)class spell lists. Any changes to true strike proposed in Unearthed Arcana would also be interesting.
This is more of a baseline than a controversial question. I feel like this is pretty clearly on-topic. It only covers the facts without mentioning developer commentary. Good answers may contain some developer commentary, but that's fine. It's a bit far from the original question, though.
Where can I find official commentary on the changes made during the D&D Next playtest?
I didn't participate in the D&D Next playtest, but I've heard that the developers released several versions, acquiring feedback between each one. Did the developers provide official responses to the feedback? By official responses, I mean articles, blog posts, and videos where a D&D designer is speaking in an official capacity about the feedback they've received during the playtest. Similarly, did the developers provide official responses regarding changes they made in response to said feedback?
If such commentary exists, where can I find it?
This feels a lot closer to the original question. I believe it's on-topic, since it's asking where to find something that either exists or doesn't. It doesn't care about what the designer reasons are, just where they are. It may need to be narrowed a bit if there are too many possible sources of official commentary. Answers may quote pieces of developer commentary to avoid hiding too much data behind links.
Where can I find official commentary on the spell True Strike?
I didn't participate in the D&D Next playtest, but I've heard that the developers released several versions, acquiring feedback between each one and providing official commentary. By official commentary, I mean articles, blog posts, or videos where a D&D designer is speaking in an official capacity about changes during the playtest. (I'm not really interested in Twitter commentary, unless it's clear that the tweets are made in an official capacity.)
Did any of this official commentary touch on the cantrip true strike? If so, where can I find it? Similarly, is there any official commentary after the playtest about true strike? If so, where can I find it?
For some reason, this one feels like a gray area. It's like asking about a specific event (the D&D Next playtest) feels fine, while asking in general terms, doesn't.
As a follow-up: what if this third question didn't mention true strike at all? Such a question seems too broad, but that's mainly because I don't personally know of a single source that contains all official commentary. It seems incorrect to judge a question's scope based on presumed answers.
Are the these similar questions on-topic? Are they also good questions?
