Guild Wars 2

While I really like the idea of Anet creating a constantly changing and dynamic world, I do not like the level of temporary content that the Living World creates. If you take a month break, for example, you may miss out on some very fun content/story. Additionally, with many of the RNG elements at play, you may not be able to get the item you want in the two week/month period.

On the idea of Fractals, and being able to play with echos of the past, I believe many of the non-repeating Living World content releases should be permanently accessible in the form of a self contained instance. Not in the five person type dungeon, but a portal-entry/exit only zone. This way, it could be set to loop through events, and allow those who missed said content to go back and be a part of the story, without having it break the flow of the main world/story.

This could allow for certain drops or some achievements to remain attainable in some fashion, as well as those who missed out on story-driven releases to experience it. Heck, even a set of minigame fractals to play all the past minigames would be a step in the right direction.
