Rogue precision?

I have a question about how precision works? If i use precision with combo points and rapid fire and I were to gain the precision crit buff from a cast of rapid fire crits, would my next crit be on a combo point builder? If so, that seems pretty worthless…who cares about firing off auto crit forceful arrows?

What level do rogues get combo points? I don’t think I got that far in the beta.

Im referring to the rogue key passive “precision.”
