Developers and game designers are running around trying to populate the Fortress, bit of this here bit of that there, put these unkillable enemies over there....
Then they have to try and actually get Eastern Solstice to work, people expect to be able to get those new skyshards, not just look at them sitting there doing nothing......
Take a day to get everything done they should have had done weeks ago! And then STILL it will not work as intended.
