Shadowform adds a significant amount of damage (15%) and also reduces damage taken by the same amount. On the downside, you can only cast Shadow and Discipline spells while in this form. This is the best soloing talent. It makes a huge difference to kill speed and damage taken. However, for PvP priests, it is not worth taking. In PvP, the priest's number one strength is his ability to heal at any time. You can't kill fast enough, even in Shadowform, to not have to heal. The extra damage and damage mitigation afforded by this spell is not worth sacrificing the versatility of having a number of different healing spells available. Definitely use it for PvE though.
