Swamp Thing > Stormwatch > Action > Animal Man > Batwing
It's a real pity Cornell is off Stormwatch. He seems to have intended to integrate the concept of the Authority/Stormwatch/Planetary together. Guess DC doesn't want to play with big ideas like Cornell's. I thought it was also interesting that Hawksmoor's city power allows him also to connect with large scale networks such as the city ship that serves as Stormwatchs HQ.
Swamp Thing I thought was the most plot heavy. The champion of the Rot is created and everyone essentially dies.
Batwing: Massacre's identity is really a no-brainer at the point. Given that he is the polar opposite of Batwing and embraced the brutality and violence that the latter has rejected. We also see a connection to Court of Owls story as Batwing makes his way to Gotham.
