My 7 star F2P R2 squad (it's not super impressive)

So I liked this event it was challenging. I had a gear 10 EP lead, G10 Vader, G10 TFP, G9 Tarkin, G7 Royal Guard. Now all of them had 5 dot health mods. They key is definitely on who you target. The aoe attacks did most of the work on Luke, Obi Wan, Han, and Leia. I used EP to shock chewie and then try and stun everyone else after. R2 is the biggest pain and almost every chance I had I would attack him.
