Come on guys quit the complaining. 1st off, he is the type of toon that doesn't change that much from 5* to 7*. But even if you really are set on 7* this event shouldn't be out of reach. Move your arena mods. Wait to get perfect RNG with lots of revives from Boba. My BH aren't great and I haven't moved my arena mods yet. 6* took me 3 tries. For 7* I will be Bossk-less but by the time I try it my Dengar and cad will be g12 and they will have proper mods. With enough attempts anything is possible.
