C3PO unlock and 7*

I have the recommended five ewoks at gear 12 (wicket, elder, chirpa, logray, paploo). In tier 7 Wicket went down in the initial rush (before any of mine got a turn), but once I started going, elder brought Wicket back and the other side never got another turn. Not certain that Paploo is essential, but Elder is (he speeds everyone up and keeps them on their feet). I think that it can be done with Scout instead of Wicket, but I think Wicket makes it easier.
