I was reviewing an item in the Low Quality queue (which I sadly cannot link to) that was most definitely not an answer and should have been a comment, because it was asking for clarification from the asker.
However, there did not appear to be an option to indicate such. It certainly wasn't ok to leave there, but it shouldn't be deleted either, it should instead have been migrated as a comment. I chose to skip it and hope that somebody with the correct privileges came along and moved it.
Should there be an option to recommend migrating an answer to a comment for those reviewing the VLQ queue who don't have sufficient privileges to do so themselves?
