Now more than ever the DCU needs Rip Hunter and the Timemasters to come back. Messing with the time stream seems to be the favorite pastime of DC heroes these days, and it needs to stop. In just the last year or so you have had time travel shenanigans in Superman, Batman, and Flash. Those are just the ones off the top of my head there could be more.

Rip needs to come back and save Booster from the character assassination that Tom King is dead set on saddling the guy with, and get some law and order back to time travel in the DCU. Bring back Waverider and the Linear Men while you at it.
