Solved the tempering and master working RNG issues by wearing 5+ unique items on all my characters. No more headaches that way. The stats it chooses to MW really do t make much of a difference either way. Most of my gear is 4/12 with a few pieces 8/12 and nothing 12/12. Pit 80 was as far as I needed to go to see that this system doesn’t really interest me.
A step in the right direction, but pointless grinding once you get down to it.
