Q:
Is there any way to redo the LS stuff?
A:
No LS content cannot be done in its exact form after it goes away. This is to keep players from leaving the game for long periods.
But Anet does release some of it in other permanent content. Many LS dungeons have come back as fractals(I am pretty sure the final fight with scarlet will come back as a fractal later this year). EOTM is a new WVW map, Tequatl and Jungle wurm, etc. I think roughly 50% of the playable content has been re-added in some kind of form.
Too late, for most things. There are some lingering events here and there. And aftermaths to explore in some maps. There are some videos you can watch that ArenaNet released. There is the Atlas, as well.
Season Two should start up soon….
Thanks for the replies.
