The increased defense of dark rage does help but it won't save you all the time and it usually takes off enough damage leaving you dead to a saber throw or kick to the face.
I have success with kicking them out of the combo (when they go into a force pull go into a jump/kick- if you time it right they might be the ones on the floor).- learn kick it is invaluable.
Switching into heavy stance and using DFA when you are force pulled also works- force pull/backstab spammers have pulled me while in the DFA animation right into them.
The best defense is a good offense- force pull and backstab them first.
