I just got into X-wing a couple months ago and have a sizeable collection, but i don't know what to get next. I have: The force awakens core set, imperial veterans, imperial aces TIE interceptor, TIE defender, TIE punisher, TIE phantom, and the TIE adv. prototype. I don't want to buy rebels or scum & villainy, as I am going for imperial and am on a budget. Also, what do you think a good list for what I have right now/stuff I might get would be?
