Best team to unlock R2D2

I had EP G11, DV G10, Tarkin G8, TFP G9, RG G8. I just ensured my mods had speed secondaries to make them as fast as possible. I took out Leia and Han first, R2 was too slow to take down first as my team were previously being slaughtered by the damage from them. I then focused on R2 and stunned the remaining toons with RG. TFP buff immunity and EP Shock were the key to stopping R2 buffing himself. I managed it on the 8th attempt.
