There are many good and thorough reports with all kinds of info, like detailed descriptions, videos and pictures... And generally speaking, when ZOS requests further info from players they do gather all kinds of data. For free and for the love our game. Player base can be really nice when treated well.
However ZOS crew members reply every 7th or so report. Knowing that each of the bug report is at least read by ZOS would mean a lot. Replying with 'it's being investigated' would do wonders too. But sometimes with bug reports, it's like talking to yourself or other fellow players who got the same issue.
