theres also the fact that it would be way too complicated to explain who the legion are and why they care about something that happened a thousand years in their past. the exposition itself could take up 2 whole episodes, never mind the explanation for the involvement. usually its because someone from their time has gone back to screw things up in an attempt to get rid of the legion but that doesnt seem to be where they are going with this season
