It would be nice if the Devs would kickstart this again if they're not going to tweak normal PvP. I remember being so excited when they unexpectedly added Guy and Kyle as hybrid lanterns. And I'm still upset about Zoom and Grodd not being added yet. Speaking of, weren't Ra's and Ivy datamined as Legends a couple years ago?
I doubt they will do anything for any kind of pvp in the near future, maybe a new legends batman skin, but that's all I expect.
