I couldn't have said this any better. As I said earlier, the management on the Green Lantern franchise has been horrendous. I really believe their terrible management and the lackluster creative ideas by them has hurt these characters in the past. So the editorial is more to blame than the writer.
But at least given that he may be continuing writing on the book hopefully (based off of his tweet), the next arc will be back to normal and it will be all John as he said a while back IIRC. We won't see these split stories like we are now.
