Ok, so far I am extremely excited, and for all those being down on the Titans and their role the whole "The League can't protect them" stuff is coming from Deathstroke, who's very jaded and obviously is biased negatively towards them. Also, so far the only casualties seem to be Chupacabra who has already gone off on his own without his fellow Bat Pack or other heroes and Beast Boy who is probably one of the Titans that would go off half-cocked. As Nightwing is a main character I'm sure there will still be a group of Titans for him to watch over and want to protect. As for the tower, it's been rebuilt before.
