I have been farming the characters necessary to unlock Rey (Jedi Training) the next time around. The vets may take me too long and I'll have to wait for the third time around. Regardless, once I get her I'll need R2D2 to get the most out of her in arena. I have no intention of farming rebels for the Palpatine event, so what's the best team to use to get a 6 or 7 star R2D2 without Palpatine? I also do not have access to Shoretrooper yet, so aside from him as well.
