Requirements from Existing Bug Reports

We have a set of bug reports and support tickets that point to a feature gap. Help me synthesize them into proper requirements.

BUG REPORTS / SUPPORT TICKETS:
[Paste summaries of the relevant tickets]

CURRENT BEHAVIOR:
[How the system works today]

Please provide:
1. The underlying user need these tickets reveal
2. Root cause patterns (are these symptoms of one problem or several?)
3. Proposed requirements that would address the pattern
4. Priority ranking based on frequency and severity
5. Suggested user stories to resolve the issues
