Well, the alternative was pretty much to roll over and die. Many in Enweil were not very active at that time, so by the time they actually got to playing The Dream, the rewards had been stopped. Attempts to trade scrolls had also proved not very successful. So while mass scroll using probably *would* have succeeded in making morale of these units low enough for them to revolt (I was told they had quite low morale), getting that many was simply not possible.
The dream rewards were never meant to be the solution, they bought time nothing else. The two solutions I can see that were possible were the books that advies could find, and the light. Mind you both are just guesses.
