Sorry, what I meant was its not split into heavy or light. So I'm assuming it's not teaching us how to craft specific armors, but instead teaching us how to increase our tiers in any armor we might know. So if we have it maxed out we can craft tier 5 armor of any kind.
That would make it a little different than what the robotic branch shown is doing, Where it is teaching you how to craft multiple different items while increasing the tiers.
