And this is where I reiterate the statement I've always made, which is that I firmly believe neither Jeremy, or Mike, or whomever have ever cared about being rigorous in their comments for Sage Advice... because Sage Advice goes against everything they believe in with regards to 5E rules. They have always wanted DMs to make their own rulings on parts where the DMs had questions... but instead all these DMs instead kept hounding them about "What's RAW?!? What's RAW?!? I need to know RAW!!!"I really want to agree with both of you on this, and generally speaking I do, but I feel like it's worth pointing out that quite a few Sage Advice bits from Jeremy Crawford have come down more on the "linguistic games" side of things than on the "common sense" side of things (particularly ones which might impact balance). Thankfully in 5E those aren't generally regarded as errata, but I feel like asserting that 5E was designed to rely on common sense is really questioned by some of the Sage Advice stuff (I avoid providing specific examples specifically to avoid re-litigating them, note).
As an on-topic-ish aside, man 5E Darkness is probably the most "more trouble than it's worth" spell in all of 5E. I haven't seen a single spell even come close to creating as many online and actual in-game discussions and confusions and "but but but..."s. And yet however you interpret it, it rarely has that much actual impact, it's just really annoying. I feel like in a few cases it would have been really helpful for spells, feats and a few others to contain a sentence or three more making explicit how they functioned. Or to have been written differently to start with.

No they don't. RAW doesn't matter in 5E and explicitly never has. And thus Jeremy et. al. I don't believe have ever cared one whit to delve down into all the niggling wording to get the same airtight definitions and crap that were the hallmark of 4E. And indeed I suspect their opinions and claims change over time because they just don't remember what they've said previously because they don't really care what they've said previously, because they shouldn't have been asked about it in the first place. And when they are called out on it, they just say "Well, it's this now" because they're tired of being ignored by people who just refuse to take "It doesn't matter what the book says... if you don't like a rule, make a new one up that works for you and your table" for an answer.
