Since launch, they've added World Ranks, Traps, Seasons, reworked the maps, added in Ruins, created the entire Edge of the Mists system and map, and have made over a thousand bugfixes, changes and minor additions. While WvW is clearly not the main focus for ArenaNet (WvW and PvP are not the majority of the playerbase), to imply that they've done nothing or don't care about it, is disingenuous.
That's not to say there aren't issues. And one would hope those issues are being worked on. I do not know what the WvW team size is, we only know that about 20 people are working on Living World, so that leaves around 180 people doing what I imagine are a thousand various projects all related to maintenance, upkeep, localization planning, infrastructure, and future features.
Just because the single thing one cares about isn't immediately being given 100% of a company's time and focus at this instant, doesn't mean it is being ignored. I understand the frustration, but devolving into reddit-style "lol anet hates dungeoneers/pvpers/wvwers" doesn't do anything constructive.
