Didn't need Rebirth, it was propped by like 15 variants. And we have seen what variants can do. That 73.9K was heavily over ordered as we saw. They can't afford to give that kind of roll out for just a decent #1. That was a poor debut given what they were putting into it. So poor they scrapped the line it was suppose to lead way too. The creative team and marketing roll out isn't even comparative to Damian's Teen Titans. Which did as expected given its late roll out. Which is not to say it did great. Thats kind of the point here, why invest more in Tim and those characters when other character can do almost just as good with less. Better even if you factor in how they do after #1.
