I haven't heard much about his return, other than the fact he judged the story contest. Sadly, he hasn't shown himself here, much. On the bright side, Xavier hasn't been spamming our forums with his TKZ propaganda.
But yeah, DAL being doing okay. It would be nice if you came back. Retan has taken over the world, Duilin has gained the ability to shift between his human side and his demon side. Zeros' has disappeared, and Jayce may or may not be about to experience death.
But yes, fightin' baddies has been tougher without your four characters to help out. Right now it's been almost narrowed down to Duilin and Ven fighting every bad guy.
