In the Star Wars Games I know, e.g. Knights of the old Republic, you had either Mind Trick as a neutral power or even Mind Domination as a dark power, with the reasoning, that, if you dominate a mind of someone, impose your will on them, is a dark usage of the force.

Thats why Jedi don't use the more toned down mind trick not all the time, only when they need to.

So I suggest to move the Mind Trick to the neutral powers and to add another power to the Light Side, e.g. to speedbuff other colonists.
