While I think everything is going great regarding current development of the game and the living world/saga should stay.
Now to the main point, many people want other things beside living story, and I am sure the company don't have enough time for everything.
Many big and small companies utilize kickstarter to fund projects.
I think Anet should use kickstarter to enlarge areas of the game, for instance it could kickstart WvW maps, a GvG project, new expansion.
This way Anet could on one hand keep with the living story that is funded by it's own revenue all the while it could use kickstarter to let player decide what is worth their investment, this way Anet could hire employs for side projects without being afraid of losing money.
