Derp... Spell check failure. "Disaster characters" should have been "extra characters". Although disaster could be the eventual outcome. :p
IG religions were pretty active when we had lots of extra characters in the game. But when you're starved for enough characters to just keep realms running, it's not possible to devote effort to extra luxuries.
You might be right, though, that the given mechanism may not be capable of providing the game play we need. It may not be possible at all, with any mechanic.
