Guild Wars 2

The whole idea of instanced DE’s would be like this: You group up with 10-15 people, and start one chain of events that could be for example free a npc who has been held by some thiefs or scavangers, than you would escort and defend that npc to a certain spot and there he would open a portal for a bigger area and there it starts. You get in with your group where another chain of events is starting. Centaurs are building some weapons you need to destroy them, after that you need to capture their camp and hold it, then you start to progress through the map, completing new tasks until you get to the very end where a bigger and more dangerous boss spawns or something else. This was just an example from different DE’s that exist now but that can be done in future more challenging, starting from level 20 or 30 not only for level 80.

A great idea but most likely wont happen, the amount of coding involved in that would be the deterrent

hmmm, I don’t know, take for example Claw of Jormag event, they could more of those pre-events and fill them into chain events that start once you enter the instance and if you fail on one of those events the whole event fails and you get teleported outside, on the other hand if you succeed you will be facing Claw of Jormag.
But like you said, only an idea on piece of paper…….
