Most reviewers are probably following the instructions in the review queue to the letter:

Almost anything can be edited by the author into something that is clear and answerable, and so, many reviewers send almost everything to the Help & Improvement queue. I know, I did so too until the H&I queue was revealed.
Those of us who follow Meta SO regularly know by now, through a number of different threads, that this is not what you're supposed to do. The vast majority of the reviewers though, are unlikely to follow the discussions on Meta if they even know of its existence.
There have been a number of feature requests regarding this problem:
- Rephrase Triage help text for "Should be improved" and "Unsalvageable "
- Suggestion for rewording of triage review guidance
- Please rename the "Should be improved" button
- Add Flowchart in Triage Review
In light of this, I think this discussion about reputation is mostly pointless. If anything, it is the instructions in the review queue that need to change.
