Well, I know about the Downvoting a question and not explaining why?, and I'm ok with that.
- Nothing constructive to say. If a user doesn't feel like there is anything for them to suggest in order to improve a question they may not see the point in down voting. If a user just going to tell you "I think your question is bad and here's why", and there's nothing you can do to improve that, then that comment will probably just irritate the question asker.
- Avoid a confrontation with the asker. Some users will get really hostile when you down vote a question, and may even insult the down voter. This situation happens more often than you'd think (it happened earlier today in fact), and I can't blame a user for not wanting to deal with that.
The main thing to remember is that a down vote is not a close vote. I down vote questions all the time which I don't think are good questions, but are still perfectly on-topic for the site. So just because your question is getting down voted doesn't mean it's going to get closed.
My question is, if there is a specific reason to keep getting DV on the question "Can a Champion jungle effectively without Smite?" *****
Maybe a chance in the patch made it look like a silly question. How could I improve it to be a better fit to the site?
