Way too many crossover stories is killing the flow of the series.
I am inclined to agree with this being a big reason for loss of readers. When you force readers who might not be interested in buying 5 titles a month to get the whole story it is a big downer.
I buy them all but that is just me.
I finally just got caught up on all my Lantern books and enjoy them (sad Larfleeze ended) but can see why some readers might not care for certain new directions.
