Isn't "abstract general subject" redundant, not to mention a bit clunky? Most Wikipedia articles describe a person, a place, a thing, etc., rather than thoughts or qualities separate from concrete reality. Therefore, "abstract" doesn't really apply in most instances where this template would be used.
The message box suggests using secondary sources for general statements about the subject, and those are sources that provide analysis, evaluation, interpretation, or synthesis. I propose changing the wording to something more like:
This article focuses too much on specific examples without explaining their importance to its main subject [...] Please help improve the article with evaluation and analysis from reliable, secondary sources to place these or similar examples in their proper context.
Alternatively, the last sentence could read:
Please help improve the article by citing reliable, secondary sources that evaluate and synthesize these or similar examples within a broader context.

Since there have been no serious objections to the proposal, I have changed the wording of the template, using the second option for the last sentence. I think also that a link to WP:NOTEVERYTHING could be useful, but I'm not be sure where. —Sangdeboeuf (talk) 00:33, 3 April 2017 (UTC)
