FOREVER EVIL
I did not read it, but I should always remember that Flashpoint means "when the hero tries to fix the timeline by doing what his archfoe always does, he f***s things up cause... drama". And time travel rules in DC comics in general just plain SUCK, the same future that has the city of the oppressed hometown of Iris Russel with limited water and resources and a military suppression, but then you have the League of Superheroes on earth.
