Having submitted an issue it would be reassuring to have an expected wait time or queue position attached to the issue.

In my experience support response time can vary from 20 minutes to several hours, at least if one can see how long approximately it will be before a reponse, it is possible to get on with other work rather than waiting for a response that may take several hours.

Obviously live chat would be preferable but something like this would probably be easier to implement for the time being and in my opinion a better user experience.
