that's the way it's always been. nu52 is actually the first time Darkseid's even been affected by a Crisis/Universal reboot. Remember the first Crisis? Animal Man's group went way out of bounds to beg Darkseid for help against the Anti-Monitor, Darkseid wasn't worried about the Crisis cause it didn't effect him in the slightest....
then he basically one-shotted Anit-Monitor (who was up until then, holding his own against multiple Pre-Crisis heroes) by channelling the Omega Effect through Alex Luthor.
Darkseid claimed to do it out of boredom and to show how badass he was and shoo-ed the heroes away.
