After seeing what we can expect from feature packs, and 1/2 a season of LS2, Its just not enough to make people come back, or keep people playing at the level where they feel invested enough to to spend money on gems.
LS2 is better than before and more interesting, but its not enough to keep many people invested.
The feature packs, so far as i have seen, do not have the type of features that would engage many people.
From my personal perspective, LS2 almost makes me want to play again, but then i just read the spoilers and figure ehh, good enough. After all, i did the first one, and while somewhat interesting after i completed it, there was nothing else in game i wanted to do. A day later or so i did the acheivs, which were kind of bleh in terms of challenge, and super ehhh in terms of rewards. Essentially LS2 is the best aspect of the current system, and its not enough to keep many players engaged.
If this is essentially the blueprint of the future of GW2, ehhhhh
