I usually borrow other people's Phasma, but I am going to start building her up again. My darkside team does not have near the depth that yours does @Predian . I still only have 5 stars on Dooku, and I don't have him fully geared. I have Vader at 5 stars, but he is not fully geared either.
I have Royal Guard, but he is not great when you are trying to 3 star a node and the darkside does not have any great healers.
