Up til today (I just Zeta'd Vader today so it may change) I ran a team of:
Palpy (L), Shoretrooper, Sun Fac, TFP and B2 and could clear GW in around 15 or 20 minutes.
If the other team has counter guys (like Fives, Dooku, Aayla ect.) then I will sub RG for Shoretrooper and sometimes Boba Fett for B2.
However, now that I have Zader, I am going to try Zader, Shoretrooper, RG, TFP and Palpy. Should be a fun time. >:)
