What to do next

So I've unlocked majority of phoneix squad, (still upgrading rex), have first order and old rebels like obi wan, leia, etc, and just unlocked commander luke skywalker. I'm currenlty trying to get gear to upgrade palpatine, vader, and grand admiral thrawn, but I don't really know which squad to chase next now. I got the bundle for kylo ren and the first order so I have that, but idrk waht to do next, could some guide me by chance about potential next decision?
