I know how you feel, felt like I had so many I have so many bronze heavies that I have to keep selling as I was farming bandits that never seemed to drop. I had a good starting run and managed to get 4 over 4 days of normal regen but when I upped the anti and used SC to get more out of 60 runs I only got 2 bandits, one at the very start of that run and one on the 58th run.

I used all my luck in the last few events where there where 2 silver drops in one map and got the perfect run 2-4 times during the events. Now I am farming witches.
