For example, "the 2 other Orr zones" are often brought up as places with very little incentive to be in (as opposed to the Cursed Shore where there are high level mats, good drops and plentiful players pushing events).
Around mid-level zones, tons of group events and major map event chains lie pathetically abandoned like a college student's teddy bears. So much content is effectively wasted. It will get worse and worse the more content they add and the more people finish with alts and mapping and move to WvW, PvP and fractals/dungeons full time.
I refuse to believe Anet didn't know this would happen to almost every zone in the game. Do you think they have a plan, or is everything fine as is, and no one will ever hold the Temple of Dwayna ever again?
