tl:dr;
One of the reason’s that Arenanet isn’t making an expension is because in expension’s, new parts are added to the world, now here comes the problem:
Adding new parts of the world spreads people more over the world, causing some parts of the world feel dead.
People aren’t coming back to GW2 because they don’t know how powerfull the living story is.
So an amazing idea is, Making just 1 expension, which doesn’t add alot of new parts in the world, just one little part, but that part does have to be good enough to make people come back to the game.
But, at the same time as releasing the expension, also release a new part to the living story.
Then, people will experience how powerfull the living story is.
I think Arenanet should think about this, because this can and most likely will work, without making GW2 feel dead.
