The way to get more feedback is to reduce the load of the individual in community moderation.
Try going to a tag... lets say Java. https://stackoverflow.com/questions/tagged/java Now, on each post on that page read it, edit it if it needs editing (this includes things like "i am trying to use a path..." - fix all the grammar (the post I'm looking at is tagged java, c#, android, .net and google maps - https://stackoverflow.com/q/49349444 ). Give a comment if additional clarification is needed.
Then go back to the tag page and see how many more there are. Repeat.
To help the most people possible, and help the people who are answering questions know which are the posts that they can help the most - vote on the questions. Up and down.
If you know it is a good question that you can decode - fix it first. People casting close votes don't see that you're trying to answer - they see an unclear post. Whats more, an unclear question (that might be clear to you) isn't clear to everyone else. You've spent a minute or so decoding it - contribute that time back to community by fixing the post. Don't leave it in a comment - fix the question before writing an answer.
Consider that if a post is getting close votes there and down votes even with the fix, it might not be a good question for Stack Overflow. Not all good questions are good questions for a particular site. One doesn't ask coding questions on Hacker News even though it may be a good question.
That a post is too easy to down vote - by percentage, down votes are a small, small fraction of the total votes cast. Up votes are 8x more common than down votes.
Improved questions many still not be a good fit for Stack Overflow. A recommendation question or opinion poll, or something that is "how do you design Amazon" is still a poor fit, even if it has been improved.
Close votes expire as it is. If its good enough, it will not get any more and there's no issue.
Down votes are a signal to people answering questions that this isn't a good question. Look at a page with 50 questions on it. Decide which one you're going to spend time on - that is likely based partly on which questions have gotten up votes.
Rewritten questions don't necessarily mean that the question is good now.
In the past, when I've down voted and left a comment I've gotten a dozen angry pings from comments from the person and sometimes half a dozen down votes on my other posts (that then got removed for serial voting). I decided not to leave comments any more at that point. I'm not there to argue with a person about if their question is good or not.
The person asking the question has all the time in the world to perfect it before posting. They can see the preview and how it will look. They can run it through a grammar checker. They can notice even things like the red squiggles under misspelled words on any modern browser.
There is no reason why they can't post a good question the first time - or at least one that shows that they have put in at least as much time as they're expecting of the person answering.
