sort of.. I play assassins in dominion and I end up with less points, because I usually prevent buff taking, or stop the enemy in a transit to prevent back-door uncapping. This gives less points than capping and defending, but it's a very important job on which my teams count on to control the middle buff and the "jungle".
you should not worry about points, just winning. I personally give up on some points by helping uncap and leaving my friend to the final capping while I go back to middle control
