Blessed Resilience

Blessed Resilience is a Tier 5 Holy priest talent. It increases the healing done to the priest by 15/30% after being damaged by an attack equal to more than 10% of the priest's total health or critically hit by any non-periodic attack.

Analysis
This talent is interesting both for PvP and PvE talent specializations. For PvP this is a no-brainer. While the buff "Blessed Resilience" is active, the priest gets increased healing, giving the priest a greater chance to survive.

Blessed Resilience has limited use in PvE - while a healing increase gives the priest a greater chance to survive, the healer rarely gets attacked, and may want to spend talent points elsewhere.
