As a force player for 8 years i can tell you that i use mostly everything. I have my techniques set for all situational. Ultimate quest per map would be fire/ice. Bosses like Luther i would have Wind/light for stuns and clock opening. Just depends on the mobs because at the end of the day I'm going for that additional damage. I do have have 3 skill tree per Force and Techter to max masteries of each element.
