The issue of where to put SG.

Originally it seemed DC's Legends this past season was going to follow a similar plan. Being new in weeks when Arrow and The Flash were in reruns. But that rarely happened. even with fewer episodes it's season is ending about the same time as the other 2 shows.
Perhaps that was nessasary because the first half of those series' seasons setup Legends.
I would prefer if we had longer stretches of new episodes. Even if it meant more than one show alternated a single time slot different times of the year.
