Would you be against or for rewarding good performance in parties?

Or Keeper of the Lake. I tell my party if they are in the middle of the fire AoE to just let me heal through it. Only try to escape if you're on the edge. Any kind of automated system would not be aware that standing in the fire is going to cause less harm to the party because it can only use binary rules.

You are thinking too simple, linear, and restricted.

The requirements for each dungeon can be based on an abstraction, maybe even an interface. It can then be implemented on a per dungeon basis.

This is why I didn't want to get into specifics as to how to implement the system. Very few players are software developers, and among those that are software developers, even fewer are game developers (again, I am not). None of us are qualified to design or implement such a system.
