Just stop trying to enjoy it that is your first mistake. Its not fun, its just a week you get to write off lol. I have to mentally prepare myself for LSTB, if I didn't I'd likely walk away.
They will release more of the characters eventually that will make it easy. You just have to wait for more of the iconic LS characters that were instrumental in the clone wars to launch. Thanks to the rebels who fought valiantly in the Geonosian campaigns I can get 4/4 with Mon Mothma and a few rebel fighters. Then there is Rey and her teams that also turned the tide against the separatist.
Kidding, but when Kam comes around maybe he will be useful and help move JKL to stabilize another Jedi team and beat more waves. That is if you were lucky enough to get double drops.. yeah CG.. it still stings.
