From an average +14 log of Prot Paladin,
30% damage reduction on RF works out to be roughly 60k dps loss in keys like SV.
I don’t think its going to actively affect Prot Paladin’s status as top DPS by that much. They’ll be roughly equal to other tanks now, but still the top damage by a smaller margin.
Strength in Adversity was an unnecessary change imo.
