The timing for Titans is bad. We have three major writers having different ideas at the same time.
Johns directed the Titans using the classic characters.
Snyder writes new Justice League books with half of the nostalgia to the animated series and the other half creating something new. So he and his team puts Starfire and Cyborg on one Justice League.
King was planning Heroes in Crisis which he asked DC for characters he can use. DC gave him Wally and Roy, so they're taken off Titans.
That leaves Dick and Raven on Titans until King started his amnesia plot and DC decided to make it long term. So now Dick's off the table too.
Normally DC will follow their TV or movie, like how they made Justice League vs Suicide Squad, Doomsday fighting Superman at the start of Rebirth, redefining Diana's origin, and pushing Damian to Teen Titans at the same time as their movies.
However DC is also the type to let their big writers do whatever they want... and they're all big writers. So while they all don't compete directly with each other, DC gave the go to all of them, and the result is split Titans in comics at the same time as TV Titans.
