It has been widely agreed for many weeks that Yavin is to be a no Armoury plant. That means if you sit on Yavin, you turn off all armoury perks, and when you attack don't use your armoury, or any restricted units.

Let's make the last couple of weeks fun. If you want to use your armoury go to another planet.
