Just understand that DC is a fractured universe, and all the worries melt away.
Are certain elements gone now? Yes. Are there new, interesting ones in thier place? Perhaps.

Keep reading long enough and you'll go through this again, just as you've become accustomed to the new status quo.
This is, after all, DC.
