most story quest have 2 path
the DoW/M path and DoL/H path
e.g.: mission r22
path 1: kill your enemy ( DoW/M path )
path 2: do your mission without fighting empire solder ( DoL/H path )

or mission r 30 where you can just fight the best or play with them...etc

I think they made it that way not to be like fallout ( where all your choose will change the outcome)
but to let people enjoy the story quest without need to level DoW/M ( for pepole who only have DoL/H )
