Yes. We are responsible for all written content and NPC interactions in the game, as well as working up item and ability descriptions, and establishing and maintaining the canon of the world. All those things are important and all fall to the writing department, though this time around we are focusing a bit more on aspects of quest writing.
Game writers have a whole lot they are responsible for, which is why there's actually pretty large teams of writers for every game that comes into being once, in proportion to the rest of the team. MMOs in particular have a good ratio of writers versus the rest of their staff as maintaining all of this stuff in a persistent world is a lot trickier than in a more "static" game; even without expansions, MMOs are having to introduce new items quite frequently, so there's that alone to keep churning out written content, plus holiday events, plus regular content updates that need quests and dungeons, plus fluffy promos for the website, and all the lore spackle to hold it together...the list gets pretty huge, pretty fast. And sadly, in some game communities, there are people who think that just one or two people can handle this load even in AAA titles, when really, even insanely creative people who can churn out content fast cannot keep up with this stuff working alone or in a pair all that easily - not at the rate a lot of people expect things!
Totally wish the writing team luck, especially the new acquisitions. I just recently found out about the game while searching for the source of a picture that had the same name but has nothing to do with the game, and I already like what I've seen, so I expect you guys will continue to do well.
