The "consistently low quality question over time" moderator template is very useful and flexible, and I've generally found a good response when using it.  I've also found similar results when using a similar template for low quality answers, and have been using it rather frequently.  As such, I think it would be useful for moderators to have something like the below added as a default template.

Sometimes users don't understand that we're not a discussion forum, or the border between "helpful comment" and "complete answer", or that we're looking for concrete and informed answers rather than wild guesses.  I think that this would be very helpful in clearing up some of that confusion.

Alternatively, [allow moderators to have custom templates](https://meta.stackexchange.com/q/212185/154510).
