I think it would be a great mistake for the Lightside to adopt the Dreamspikes, because there will be that basic lack of knowledge of the other sides' tools.

What better way to undermine your enemy than to make them think they've usurped your plans, only to find out that you planned for it all along? Actually, Morondin/Ishy has always been big about talking that way... Whether or not it's true is another thing...
