Tips
Renew is generally one of the most efficient healing options, and has the bonus of being instant cast. Its main down-side is its slow and relatively insubstantial healing. Using Renew pre-emptively or on non-critical targets is a good way to make the most of its efficient healing, as well as insuring them (in a small way) against incoming damage. However, Renew's efficiency and desirability is significantly determined by the priest's haste.

Renew has advantages besides its efficiency. As an instant heal it can be useful in PvP when interrupts would prevent a cast-time heal. It can be cast while running and can be placed on multiple targets very quickly. As an HoT it is also a useful way of insuring against silence effects and stuns. Renew can be used whenever incoming damage is slow enough to allow for its use, saving mana otherwise spent on more expensive heals. On the downside, as a magical buff, Renew has the disadvantage of being dispellable.

The concept of putting Renew up on as many targets as possible is known as "renew blanketing", which is a very potent form of healing, but also very tough on the manapool.
