I've been potion master for the past 3 months or so. And making anywhere from 20-100 potions a day usually my proc chance hasn't once been 15% or lower. In fact about 3 times out of the 80 or so days I made them was it even under 20%. Is this just a random string of luck or have they changed the proc rates?
Edit: For those misunderstanding, I'm proccing at around average I would say 22% over about 2000 potions. I'm asking if they in fact buffed the percent chance, not nerfed.
