I don't see a lot of questions. Mostly statements of absolute fact and definitive solutions. The current design objective quite clearly seems to be that objectives should be the primary concern (in certain missions). Not fighting. Retreat achieves that, somewhet inelegantly. If you think the design objective needs to change, it needs some pretty good backing as to why. Since we already know removing retreat functionally fails at achieving that objective. But I think this line of discussion should go to another thread if you do intend to provide that thesis and I'll be happy to discuss there. This thread probably has had enough retreat discussion.
