Have you ever noticed that it seems like Medium Armor doesn't get any respect in the game? Not that I use it, myself, but I'm really talking about the materials for crafting Medium Armor. When you get a survey report and use it, you get 4 Light Armor nodes (plants) and only 2 Medium Armor nodes (traps). And if your Medium Armor crafting level is below your character's level, you get only 1 Medium Armor node at the material level that you really need, plus 1 Medium Armor node at your character's level. Of course, it's easy enough to run around killing wolves and mudcrabs to farm Medium Armor material, but I'm just saying.
I've fought mudcrabs more fearsome than me!
