James Robinson is leaving the Earth 2 title

And he says so himself on his Twitter page:

And he's even leaving DC behind, I see. At this point, I'm quite fine with that. After he went miles out of his way to shove "diversity" down everyone's throats by turning Alan Scott gay and wiping out plenty of better history of the Justice Society, I'm not sorry to see him go. In the end, he only turned out to be one of many modern writers who didn't have much affection for the heroes and supporting casts they were assigned to write, and didn't have much faith in their own writing to start with. In that case, they shouldn't have even bothered to take the assignments if they're not dedicated to entertaining anybody.

So, Robinson won't be missed, and I won't be surprised if the Earth 2 series is destined to lose more readers and sales than it already has.
