Playing in Torment 1+, I have rarely gotten any plans for crafting blacksmithing gear. However, I noticed while farming for a Ring of Royal Grandeur on Normal that I received a number of plans (somewhere around 6-8) and few non-plan drops. I'm curious if anyone else has experienced this or it's merely RNG. Theoretically, it would make sense as that you aren't eligible for the Torment drops, and numbers could be adjusted by Blizzard so you could upgrade several slots through a single drop.
It's all RNG. I've gotten most of my plans in Torment difficulty, but I got my Wall of Man plans this morning while doing normal bounties. Again, it's just RNG like every other drop in the game
