Other than what was done through the game's story, there really hadn't been much done to hype people up for the new expansion. End of Dragons does seem really interesting and does seem like it'll be a blast to play, but with barely anything to go off of, I do worry a bit it'll not meet expectations. I'm not going to be one of those players that straight up say it'll be bad because, honestly, that's a bit of a kitten move to both the players who are excited for the expansion and the devs but I do hope I'm not the only one that is just a bit worried about how the new expansion will go.
Other than that, though, I am, genuinely, excited to see what GW2's version of Cantha will be like and how all the e-specs will play out. From what I've tried, Specter seems to be rather fun, same for some of the others, however flawed they may be. Some felt questionable but I assume they're tweaking them to be better.
