Just adding a vote here - love the updated Destroyer's Factory and Andrith Ruins and the fact that they are easily visible and encouraged to be done thanks to the new daily missions from Lt. Morrigan. TA is also really fun.
Please consider, if you are not already doing this, updating the other lairs in the game to also be possible to run for all levels up to and including 40, with similar daily missions. Please also do Stronghold as the next one if possible. :-)
