Yep. Exactly. They have equal odds of being good or bad whether they come before or after Justice League. But they have better odds of making more money after they hang out with Batman. It's pretty simple. Marvel needed to, WB doesn't, so they won't.
And about the introducing mythos deal, that's what writers are for.
