I unlocked (5*) him with Teebo(L), Wicket(z), Paploo, Elder and Scout, all gear 10, it was pretty hard but not so much, I killed first The rebel commander, Chewie then Han
I unlocked 6* 3Po with Teebo lead (G10), ZWicket (G10), Logray (G9), Elder(G9) and Paploo (G8), managed to get 3 star on the event too, will need to gear these over the next 6 days to get 7* but surely you can 7* it with Teebo lead
I beat tier 5 with g11 Chirpa(L), Teebo, Elder, Scout, and Wicket. Most around ~200 speed and no zetas. May be able to get a zeta for Chirpa before the event ends, haven't tried Teebo lead yet. Don't have Logray or Paploo so the Teebo lead may not work for me
