Six metrics feels like the right amount. I’d support this if it replaced rather than removed.

“Remove “Pro-Royalty” and “Anti-Royalty” from the stances of all Editor, including idle ones.”
Rule 1.2.1 Idle Editors: “When an Editor is unidled, if they went Idle in the same dynasty, their personal gamestate retains the last legally endowed values it had, if they are still valid.”
Doesn’t that mean an editor’s personal gamestate ceases to exist when they go idle, and reappear at the value it had when they idled when they deidle? In that case your provision wouldn’t be effective.

But they won’t still be valid, so it seems still covered.

Does feel like we need at least six subjects, even if this one isn’t great.
