I usually build mine 3 different ways: either each unit is specifically tailored to do something, i build around an 1 or 2 major units like jedi or tanks, or my favorite, i build thematically. Example: if i want a ryloth list i throw cody or kenobi with waxer and boil in my phase 1 squads with at rts. Building lists after armies in clone wars episodes is a super fun way to play
