Eventually there might be one. But currently I like the way things are. Also, I prefer that the better blueprints aren’t sold at npcs and only can be obtained as a drop from certain mobs.
T1 drop from all mobs. (Chicken and Sheep I think only drop hatchet and Poinard)
T2 drop from Fierce Wasps, Hornets, Ghosts, Goblins and Swamp Troll. They also Drop T1. Swamp Troll and Ghosts are the best to get a T2 blueprint from.
