I read a Seeley quote about Grayson somewhere: he should be “ the nice Nick Fury”
Hell yes. He knows everyone, can go anywhere, is a proven combatant and leader, with far superior people skills than his mentor.
I sincerely hope DC can work it’s way back to positioning Dick exactly like that. As been said before, Nightwing doesn’t have to go away.
But Grayson needs to grow.
