Trick to keep in mind+3 XP
Length and uniqueness beat complexity and rotation.
Forced symbol rules and regular changes push people to predictable patterns such as a season plus a year with an exclamation mark.

Rotating only when there is a reason, such as a breach, stops churn that people answer with minor edits.
