6* Dooku lead (VIII)
7* QGJ (VII)
5* Fives (VIII) I can switch out until I star him up?
6* Savage (VIII)
7* Kylo Ren (VII)

Got lots of Toons I can switch in for better synergy if needed. Any improvements needed? Should I switch out Fives until he's got a high star?(GS, Rey, Phasma, Yoda etc.)

Kylo and savage are terrible I'm arena. You need some higher damage characters, and a taunter (RG or STHan) and probably a controller as well. Fives is also not great at 5*. Work towards something thing a bit like: Dooku (L), rey, QGJ, STHan, Daka. Eventually, you might want fives back in, but personally, I wouldn't do that.

Instead of STHan I'd suggest Royal Guard. Both he and Daka can do stun. But the rest seems like a good suggestion. If you do not have Daka, I would suggest Lumi for some healing potential.
