So I was lurking in the Deathstroke thread since I'm thinking on catching up (I only have the first two volumes) and someone said that Priest requested to work on Nightwing and Didio said no.
We are in the worst timeline.
Failing that, I'd like to see him tackle an adult Titans book with Dick and any Fab 5/NTT members available to him. Anything would be a step up at this point
