Curious what product field was for your experience? In my experience, support issues tended to involve legacy application technology and/or environment issues (usually antivirus given the nature of our product). Support for anything non-trivial involved WinDbg dumps or SQL dives in cooperation with development. Did your support experience include working the issue back through development for a hotfix and retest until resolution?
