一、 Class Overview 职业总览
The Discipline specialisation relies on healing players through dealing
damage (thanks to the Atonement Icon Atonement passive). This allows them to
contribute to the raid's DPS while still performing well as a healer. From a
strictly healing perspective, Discipline Priests will be below the other
healer specialisations, but they compensate for this with the extra DPS they
bring.
戒牧靠着造成伤害来治疗队友（因为赎罪被动），这使他们能在当个好补师的同时还能
替团队贡献DPS。如果只看治疗的话，戒牧排行是在其他补职之后的，但他们制造的额外
DPS能够补偿这点。
Due to their reliance on DPS, Discipline Priests suffer whenever there is no
target to attack.
戒牧很依赖DPS，因此没东西可以打的时候会很麻烦。
