Now that the close system is a lot more user friendly and encourages people to edit their questions, I feel like reviewers are missing a crucial option.
When a question has been put on hold, say for "unclear what you are asking", the user may provide more information that clarifies but means that the question is invalid for another reason. When reviewing the request to open, I'm only given the option to leave closed, which presumably gives the impression that the question is still not clear enough, whereas what I actually want to say is that it is off topic or similar.
