Really frustrating though the royals have to be shafted for the sake of Twilight&co though.And also poor handling of them if they aren't allowed to do anything because they aren't the main characters.Luna's case hurts worse than Celestia's since while Celestia managed to protect Equestria for a 1000 years(no way in hell there wasn't any threats popping up during the 1000 years gap) on her own, Luna's track record looks worse in comparison due to losing a 1000 years. And the fact since her return from the moon, she just kept getting sidelined or taken out.(In this case its worse with the royals are still shafted even when Twilight&co gets taken out. They could have it so Luna at least got to shine there too, as in not get captured, at least to make up for apparently she freaking slept through the changeling attack where her sister was in danger)
