Good initiative for reporting, we will definitely need this later on. My concern is that the user will probably get confused on the type of report to use, and make use of the wrong report for the wrong scenario. This would need correction, such as further explanation etc, of which would require precious time and effort from the developers, something that can be avoidable.

Instead, we could make use of the labels, as we are currently, and merge the Bug Report with Discrepancy Report into a Problem/Incident report and Game Request with Modding Request into just Request, to streamline the reporting process.
