>>101096706Why does the modern Legion of Doom include Joker, instead of Scarecrow?
Scarecrow brings pretty much the same things to the table in terms of mass terror, psychology, and exotic chemistry, but he's someone you can imagine actually being recruited into and working with a group, and he was ripe for a big push and redevelopment after Arkham Knight, Gotham, and Injustice 2 all featured him in a big way.
Joker will just inevitably turn on you or fuck up your plans out of whimsy, and has no interest in anything but Batman. He's a shallow hype pick.
