I don't have the campaign rules in front of me, and couldn't find it in the Learn to Play guide, but how many of each deployment can the Imperial bring to the Open Groups? I'm been told as many as the expansion provides, but what about when the figures come in packs? Are you only limited to what comes in the packs?
I can't say I recall reading this limitation, but its always referenced as fact in my play group.
This is of course barring house rules.
