I mean, I think everyone here probably knows that I loved Tynion's run on Detective passionately. I think his work with Steph was the weakest (well, that and poor Luke, who I love), but it still had some really good stuff. She got her relationship with Tim back (which was abrupt, and was too much of her characterization, but I still think it's really nice to get back, since it was a huge part who her history), she got to prove she's not incompetent, and she got to see her history as Robin and Batgirl.
Batman got to hug lots of people, got beaten by Shiva, and showed that he was able to inspire and train his team.
Batwoman got some really complex development and a huge supporting cast upgrade (I know it was controversial, but I loved the Colony and think it's very much in line with Rucka's trajectory for Jake, even if Rucka hates that Jake and Martha are siblings).
Tim got to be Batman's loyal right hand, an idealist who screwed up, and he got Steph back.
Cass got Clayface and a working of her death wish/self hatred stuff.
Clayface got a huge story of trying to be a hero.
Jean-Paul got his dual nature of gentle, faithful guy, and BOMBASTIC AZRAEL, plus Batman software in his brain and genetic engineering, like he originally had.
Luke got awesome gadgets, his sister Tam, and Rookie!
