77,000 is high, if you consider that they came back after they werent in the comics for long time and they didnt appear in a Major Book like Superman or Action Comics at their Comeback.
The drop could have several reasons.
Like I said I like the YJ4 core characters, but I dont like the actual series.
Most recognizable forms ISNT TRUE!!!
-Cassie got a new outfit,new origin and lasso without powers and also her attitude is different.
Cassie is like a complete NEW Version of herself.
I am VERY disappointed by this
-Conner has a new look, based on his first costume, his attitude is bit based on Kessel...
I also would say that the Johns TT Version with black shirt is the more recognizable one, since he wears it also in the Anime.
I dont like particulary his appearance and attitude.
I would have prefered the more muscular Conner with more attitude.
So Cassie is (for me) a COMPLETE NEW Version of herself and this Conner is also kind of new for me...
-Red Robin worked well in Pre-Flashpoint (Outfit with the cowl)
I like this outfit more than DRAKE outfit which I find horrible, because of the colors etc.
As far as I understood there will be a general aging up because of 5G, which would also mean that Tims Generation will become older and be the age class between TT and JL.
I hope that they will change the direction of the current YJ Series soon.
Like I said already I dont like the actual storyline, because I feel like its leading nowhere and it isnt a major storyline...
The ANIME YOUNG JUSTICE works better, because it let the Teams grow up, become older and take over more mature missions.
