The original point of the post is a good one, and yes raised a long time ago. But it is very relevant to people who have only started playing in the last year or so.
The difficulty of the territory battles is clearly the same as the order they were launched:
Light side Hoth (LSH)
Dark side Hoth (DSH)
Dark side Geonosis (LSG)
Light side Geonosis (DSG)
The problem is that when a guild is in the middle power level they can't do both of the mid difficulty territory battles, because they run at the same time.
They don't need to do anything as complicated as making them all optional every time. They simply need to swap it so that light side Hoth runs at the same time as dark side Geonosis.
That would allow all levels of guild to do the territory battles appropriate to their level.
Low guild: LSH, DSH
Mid guild: DSH, DSG
High guild: DSG, LSG
