Please help my squad development, I went down the random line! Need to salvage my squad advice.

One more question when I’m told to farm Ren unmasked does that mean continue to farm him until he is 7 star? Thanks guys I’m going for the droid ship and maxing Ren. Got akbar too so my fleet getting bigger. Trying to only focus on my light and dark side top 5 players now. Superb advice, thanks again! Please feel free to look at my stuff and make any other comments...I’m still saving my revenue/energy for later in the game.
