I used this
I'm not sure if that is doing what I think it should do though if anyone can comment on it. If that is using Focus Fire only when the Rune procs, then it works out to a DPS loss of 5k over using Focus Fire normally with the Rune equipped. Intuitively that doesn't make much sense to me. I was thinking it just wouldn't have a large enough effect to make it worth using over other trinkets but not an actual loss. Using it normally, Focus Fire was used 6 times. Using it only when Rune procs, Focus Fire was used 10 times. This made me think using Focus Fire below 5 stacks is leading to the DPS loss. I ran the simulation again using
This gave me the error "Acceptable values for 'five_stacks' are '1' or '0'"
I tried switching the conditions around
This caused the program to crash. Anyone have any idea how to make simulation craft use Focus Fire only with 5 stacks and only when Rune procs?
