1) Where is the promotion for the book?
2) How fans in general has DC chased off along with the constant questions about WHO is in charge?
3) Maybe it is more of none of the derailments that got everyone else have not hit Nightwing. And yes we saw other Nightwings in the book but none were trying to take over while Dick was still trying to figure out who he was.
4) Top 100? WHO CARES? How many books are pulling their same numbers or near it and getting PUSHED down by nonstop event mess? Along with certain variants boosting a title here and there and along with new books coming out.
Not being in the top 100 does not mean it's a horrible book no matter how many folks want to scream that as a battel cry to get writers fire or keeping books NOT starring straight white males from being made.
