As Priest being a class which is fairly old in the game..the skill descriptions for some of the skills are very basic.While other new classes in my experience like charmers have skills very descriptive..stating the % of the crit dmg,block,stun etc.
My suggestion would be to update the descriptions aswell so it would me more easy for us to know the exact percentage of the buffs we get.
Ps.I want to know the % of god's help crit dmg.
