its not a problem. C3P0 just forces people to try out different squads in arena. I for one am glad to see Traya teams die so quickly to Rebels and Resistance. Revan is still good vs zFinn and Bastilla is really good vs the team also. I run a zFinn with Raid Han, Chewbacca, RT and C3P0 and I can't beat the Revan teams every time. Also its scary going up against other teams with raid han since you never know who's han will shoot first. Its 50/50 at that point. Maybe try switching up your lead to counter the emerging meta?
