Yeah, it's definately a mystery as to how the procs work in this game. The doffs I'm testing don't act that way, but they do seem to proc two and three times more than 9.6% and .8%. You don't suppose the system is adding and giving each of them a 60% chance to proc do you?
I've done no controlled testing, but doesn't getting hit with VM buffed by three doffs feel like it procs closer to these percentages? Having at least one proc should happen less often than not, yet I find it rarely doesn't proc at least one.
