To be fair, extraordinary things in general are by definition relatively rare. But yeah, there was no DKR-style defining moment, just a bunch of solid books, like you said: DC Comics Presents, Arak, Don Newton's work on Batman, The New Teen Titans, satellite-era JLA and so forth.
I do think the Conway run on Batman is unfairly overlooked, perhaps because of some unfortunate Irv Novick/Frank Maclaughlin artwork.
