I also voted for something else. As the originator of the idea, I meant for it to have an effect similar to an Invasion. In order to stir things up every now and then, dramatically increase the spawn rates of everything until the island is swarming with them and things start to fall apart, then crank it back down. The idea would be to not let things get too settled and locked in to a particular power structure.
Maybe the strongest realms and power structures would be the ones to always survive and nothing would change, but then again maybe not. Enweil used to be the reigning power of Beluaterra, but the Invasions eventually crippled them and opened up opportunities for other realms to take their place. This is a good thing for the game. Just look at how Thalmarkin turned things around between the Fourth Invasion and the Fifth, or how Riombara came to be the dominant power in the southeast. This sort of dynamic turnover is a good thing.
