So I've got Finn, Rey and BB8 all 7* and plan to have Rey and Finn G9 with rest G8. I only need to get Rey to G9 basically, but I could leave her at 8 and get Finn to 10 instead. However my vets are quite behind. Chewie is 15/30 heading towards 4* and Han is 2* 1/25. Will I be able to finish them in time with 1 refresh a day?
