Last expansion they did two dungeons for even(?) patches and cut back to one dungeon on odd patches in order to devote more resources to the Ultimate raids... so I can only hope that whatever resources they're freeing up from this will be going to bigger and better things (I myself have a stupid hope that it'll go to finishing the Viera and Hrothgar though it's likely not the case). IDK, it just seems that we're getting less and less content during this expansion. RIP my dreams of seeing a Shisui or Bardam's Mettle Hard Mode.
Oh well, I'll be okay with it as long as the gear sets that drop aren't recycled from older gear.
