As a thank you and hint to other new players:
As soon as one hits 100 with their first toon, the best course of action to find blueprints is indeed farming SR Normal. Provided that the char is well rounded (with capped Resistances + adequate OA/DA/Armour) one could easily delve quite deep into SR Normal.
With my Witchblade, managed to consistently farm SR 75&76 Normal and after some 30 Runs gathered the recipes I needed and then some -> without logging out (as to avoid duplicate farming), managed to also horde in an impressive 91 Legendaries.
Thank you all for the help and have fun playing Grim Dawn!
