Trusted/senior users (narrow focus)

This observation fits my experience with administrators: they should not be involved in content disputes as administrators (of course, they can add their two cents into a Talk page like anyone else). Creating a set of "higher" authorities is a prescription for disaster.

The best way to handle quality issues is a strict enforcement of guidelines on Talk pages to insure a constructive exchange focused on topic. That means a robot-like universal enforcement of WP:NPA WP:Civil and so forth applied to every participant, regardless of the Admin's view of who is right or wrong (the Admin usually can't tell accurately). It also means strict patrol of slurs, sniffs, catcalls and other such techniques used to inflame discussions and sidetrack issues.

If the Talk pages worked correctly and avoided debates for ego-satisfaction or entertainment value, article quality would improve, and tiresome exchanges and disciplinary disputes woudl be reduced.
