Guild Wars 2

Here is my prediction:

Much like how an Asura laser killed Zhaitan, Scarlet is designing a new super-mega laser to kill the dragons.

The thumpers are designed to disrupt and redirect the flow of magic contained in the ley lines around Tyria. It is this magic she intends to use to power her mega laser.

Since elder dragons are intended to consume magic, they will be drawn to Scarlet like a moth to a flame.

The epic conclusion will result in 3 elder dragons appearing that we have not seen before! After an epic cut scene where we get to see them in all their glory, Scarlet will come down and nuke them with her new weapon, destroying them.

Reasoning: It fits the ArenaNet paradigm: create content with the potential to be excellent, only to completely destroy it with terrible implementation decisions.

I was under the impression that was the real manifesto
