Personally, I mostly stopped playing GW2 before HoT was out; all that was keeping me in the game was my foolish quest to get a Legendary (not even grinding for gold initially, but that ended up being the least painful option in the end), and doing Guild Missions with my guild. I just couldn't handle the grind anymore. Doing World Completion was the first downhill slope, and I didn't feel compelled to do any of the other content because what the team considers "fun" and "challenging" seems to be mostly incompatible to what I feel.
I was hoping that Heart of Thorns would bring back some enjoyment to the game, but nothing in the expansion feels like it's gonna make me enjoy the game again (judging by this post and what my friends and guildmates have told me), and that's a real shame, because I really liked GW2 before I hit the end-game.
Guess it won't tear me away from Final Fantasy XIV any time soon after all.
