So, here’s the thing.
The fact that a type of play doesn’t make sense to you in D&D 5e, or that it didn’t work for your group, doesn’t mean that it doesn’t work in D&D . It just means that it doesn’t work for your group.
Telling someone, without any explanation or reasoning, that D&D doesn’t do a thing that they’re asking for advice to do in D&D, is dismissive and rude. It isn’t advice, it’s threadcrapping.
Telling someone that it hasn’t worked for you, or asking them what they want from a horror D&D adventure or heist D&D adventure or whatever, that sort of thing, is advice. Very useful advice.
It’s “D&D 5e doesn’t do naval combat. It won’t work. You’re better off finding a naval game.” Vs “Naval combat hasn’t ever worked for my group, because XYZ.”
Because the first is just false, because it’s an absolute statement. The second is obviously true, and useful advice.
You don’t know what will or won’t work for the person asking for advice.
