Hate gives force on damage, Maul crew does the same with stress and damage, and the Senate regens a friend's force should he stress them. Grand Inky crew stresses himself to react, whilst 7th sister crew turns a situational bad condition into a worse one. The Senate could stress the attacker while using the force. Obviously the Dark Side (in the game) is defined by force being correlated to negative effects. (Is this, given Windu's tapping into the dark in combat, why his ability is so?) And would you look at that, the only Kylo build that spams his ability is the one that regens force on damage to show people the dark side.
When can we get a light side-specific card? Perhaps in the new Y wing, for it seems that a theme is rising. After all, much of the light side abilities are spending the force to distance one or others from a negative effect. Kanan and Luminara decrease the intensity of enemy attacks on friends. Kanan crew increases the blue on your dial. Luke gunner means no losing a target. Obi wan makes sure that you won't be caught tokenless unless you have to, Ahsoka lets you act even when stressed, and Anakin removes stress. Sassee can correct your trajectory. And Plo of course, looks out for his bros. Battle meditation is, like many of these abilities, purely supportive, but also faction-locked.
