Personally I prefer the Living Stories. I would not mind LS only going forward as long as it affords the same opportunities that an expansion does in the long run. I have noticed that when you get an expansion, that there is a core group of players that will blaze though the expansion in 2 or 3 days; go on the forums or social media and talk smack about it, give away spoilers, etc,. before the casual players have even had a chance to get really started. (happened with HoT and to more of a degree with PoF). Then they spend the next few years griping about the expansion and how the game needs another expansion because, in my opinion, they need some new material to gripe about because their main cause is petering out.As long as ANET (looking at GW2 developers) is consistent at releasing new LS stories, the "we need an expansion" people should be happy, unless you are in that special niche that needs to burn through content to ruin it for everyone else.
