Combo point question

Is it a dps loss to dispatch at 4 combo points or should i waste a point and go for 5? What about Sin?

It’s generally accepted that using 4CP is preferable than wasting in Sin. I’m not certain about outlaw, but would love to know assuming it’s lower risk to over-cap.

 As assasination use all finishers at 4. Garrote for 1 cp or seal fate proc to make it 5. Using mutilate or toxic blade at 4 you risk losing combo point on a seal fate proc. I dont have much experiance with outlaw but I know you want to dispatch at 5 especially with blade flurry up.
