Question: Does Heavy Armor within the most recent edition of Blades cost 3 load points to carry, or 5 load points?

Question: Does Heavy Armor within the most recent edition of Blades cost 3 load points to carry, or 5 load points? The way I see it, you would add the three boxes of “+heavy” to the cost of regular armor, costing you a total of five. However, some of those I was playing with did not agree, insisting that heavy armor costs 3 load points, and that the heavy armor cost should not be added to the normal armor cost. I cannot find a definitive answer anywhere else, so clarification here would be appreciated.
