Don't get me wrong, the book sucked but Lobdell shares the blame with the slapdash, haphazard continuity that DC created. You cannot build a teen team whose characters rely on their connection to both the wider DCU and very specific characters without first fleshing those relationships out. DC did not do this. At all. Everything was up in the air at the beginning of the New 52. All of Batman's stories are still canon, right? DC said yes... Then it said no 12 issues in. How long had Bruce been a crime fighter? Jim Lee actually said 10 years! ooopsies! Are the Kents alive? Who knows, Morrison is not telling anyone (including the writers of Superman!). Where is Diana? No one knows because she is, for all intents a purposes, off on an Elseworlds adventure and does not interact with the DCU proper for 30 issues. Tim was Robin, right? Lobdell thought so. The Bat Office retroactively disagreed. Was there another Teen titans team? Lobdell and Johns thought so but Editorial retroactively said no... Then four years later retroactively said yes! Green Lantern wasn't rebooted, right? Well... It is complicated, so complicated that it is best to not ask questions. Where's Wally West? DC said he wasn't coming to the DC, then they created a new character that used Wall's name.
The list goes on and on. DC had no idea what they were doing at the beginning of the New 52. They just needed to shove books out and sort it all out later. Books that relied on continuity the way a Titans book does cannot be successful in this environment. If everything is up in the air, then your hands as a writer are tied, since anything you do say or do with a legacy character/sidekick is libel to be retroactively altered.
It would have been better if DC had not used any legacy characters for the new Titans and instead focused on characters that came with less baggage (i.e. Raven, Beastboy, Bunker, Blue Beetle, Gnarrk, Lilith, Starfire, Static, etc.)
