Discipline Priests have been completely overhauled in Legion and Shadow Priests are mostly just a ranged DPS class now.

"The Discipline specialization relies on healing players through dealing damage (thanks to the Atonement passive), but also has traditional heals and absorption spells. Healing through dealing damage allows them to contribute to the raid's DPS while still performing well as a healer. Discipline Priests provide the greatest burst healing in the game, and they are also able to contribute DPS to the raid.

Atonement: Plea, Power Word: Shield, Shadow Mend, and Power Word: Radiance also apply Atonement to your target for 15 sec. When you deal spell damage, you instantly heal all targets affected by Atonement for 40.0% of the damage done."
