One thing I finally realized today was the Big bad guy behind EVERYTHING in GW1 was the former human god, Abaddon. Didn't realize until now he was behind the Searing, the Cataclzym, the Jade Wind, and Varesh's take over of Elona. So basically EVERYTHING that went wrong, went wrong because he controlled key evil figures as well as the Titans.
Once the human Kormir took Abaddon's place, the six human gods were restored, but it does beg the question, where did they go in the last 250 years? Was it because the Dragons are waking that they left, scared? Or did they leave to prepare and come back? Or did they know they weren't as strong as the dragons and gave up?
It's very interesting to realize that GW1 the main bad guy was a twisted human god and now in GW2, it's the Dragons that are the main enemy. But in GW1 players didn't know for a long time who the true enemy was. Are the Dragons just the minions of some one else? Is there another evil puppet master behind everything?
