After reading about the problems McDuffie had with DC regarding the League's roster, it got me thinking why not just have the Justice League book be in a separate or quasi-separate continuity. I mean, one of the major selling points of the JLA is having all of your major heroes in one book, especially if you can't afford to buy their individual books. But by tying the JLA so closely into continuity, or attempting, with the other DC books, I could see why McDuffie was so frustrated when he couldn't use some of the bigger characters. Though I wound up thinking the ones he got to use had the potential to be an interesting team. But the problem could've been avoided if DC had just divorced the major characters from continuity obligations. That also could've freed them up for Robinson if he felt inclined to use them.
McDuffie wrote about his problems with continuity here and his ideas here.
Thanks Shivkala. That was really cool. I think McDuffie was on to something regarding each book having its own continuity.
