Test your setup
Balance critical rate with critical damage. A large damage number is less useful when critical hits are inconsistent; evaluate the complete setup rather than a single item.
Choose one option, run the same encounter twice, and change one variable. Record whether the next rotation starts on time and whether the team survives without losing its damage window.
