I have one minor gripe with the DLC. Why the heck would my character be considering joining the Titans? Any hero over Level 30 is already a member of the Justice League, with the full approval of Bats/Supes/WW. So why would the character need to hang with a bunch of kids? To my mind, a better intro would have been something like, "Hey, we were having try-outs for new members, and something seems to have gone wrong. We need adult help here, to fix it. Please." and the JLA assigned our characters to look into it. That would also explain Damien's bad attitude - he doesn't think they need any help, because (realistic teen) he knows everything.
