Fast answer
Treat Gold Rush as an efficiency mode. A stable clear team is usually better than a risky high-ceiling team that resets too often.
Why players farm it
This mode is attractive because it can turn a calm, stable team into a reliable farming route. It is most rewarding when you treat it like a repeat session, not a one-run challenge.
Best approach
Favor stable pressure, not panic damage. A team that can run Gold Rush over and over with clean timing is the one that gets the real value.
