yeap Nightwing gets burned again for still being sidekick. Because " he's gotta be so close to the overcrowded family" right? He can't even have his own narrative and place.
So we lost Grayson for this. Nightwing couldn't join JL:O because that's not Batman lite enough.
This is not the 90's red hood is here, let him do the dark gritty street thing. Nightwing (like the person got the name form) should be about crazy epic adventures, just like his sliver age robin days, NNT days and Grayson.
We don't need Batman lite the sidekick any more. Especially with all the bats we have running around now.
