Also I would like to add the reason I use divine protection after ardent defender has proced is because you lose the damage reduction you receive from it when you die and don't get it back for 2 mins, you only res with hakf your health back so using divine protection there makes the most sence, for all other times you should be keeping divine sheild up to help reduce damage.
If things start looking hairy I will pop divine protection put to me it is a wasted cooldown to do so as it means I can't use avenging wrath for 30 secs and I can't use lay on hands, I can't even use bubble hearth for those really bad moments =(
Also since jonnie has replied since I did this message I would still need to check his gear before I make a decision
