Its a decent comp, although not top tier. In most matchups you wanna bleed up both targets and try overwhelm them with pressure. Kill targets and cc is very situational and comp dependant. Just be careful not to spend too much time trying to make the perfect setup at the expense of keeping pressure up. I recently made a pretty extensive post on the priest forum in the “2s help” thread that your friend might wanna check out.
Make sure you have macros for focus root and cyclone, and party1 thorns.
