Shouldn't Black Flame's Protection be put under Barriers, rather than Greater Barriers? It has the same DR value as the lesser ones, at 35%, rather than 60%, like the greater ones.

They were categorized based on their durations and FP costs. And while it is the same value, Physical damage is a much more common damage type.
