I have to agree with you there. Winnick laid the groundwork with UtRH but unfortunately no one was willing to pick up the ball once he dropped it and that lead to stagnation for the character over the the course of years. Jason during that time had very little in the way of appearances and also had some very inconsistent characterization on top of that. Another problem was that no one seemed to be willing to allow Jason to deal with his PSTD issues and his issues with Daddy Bats and family so just about any time he made an appearance in a Bat title he was always harping on the same issues without getting anything in the way of resolution for them. That got old fast.
I would have been happy enough to read a series that featured him as a villainous vigilante after UtRH if they had taken the time to build up that direction and had given it to some writer that actually wanted to write it but they never did anything interesting with the concept at all. (I am aware that there were plans back at the time when they were considering killing off Dick Grayson to replace him as Nightwing with Jason but that didn't pan out.) In the end it became a direction that had no legs at all the farther they got from UtRH and something of an albatross for the character leaving him unable to move forward in any meaningful way.
Honestly, Lobdell at least had the gumption to try and move Jason beyond all of that nonsense and into a place were the character can move forward. I never saw anyone in the Bat office even try back in the day to do so. In my opinion that makes Lobdell a far better custodian of the character then the greater part of the Bat writers back before the reboot were.
I agree with this as well. Likely editorial sees potential in the character and book and a collection of anti-heroes lead by Jason, who is the most well know DC anti-hero or close to it anyway, does fill the void between something like the JL and something like Suicide Squad.
Honestly, not one writer in the N52 has managed to make Teen Titans work so I don't think it was only Lobdell who is at fault there. I'm not expecting much out of Percy on that front either to be honest. Also as an aside is your Avatar Jon? I've been meaning to ask.
