This is going to be a brief guide to understanding probabilities within DCUO. My hope is that it will help give a bit of perspective on how drops/breakthroughs/etc are determined in DCUO and help give a starting point on discussions around drop rates/potential issues with breakthrough/etc. I’ll be going over how “random” aspects are determined, examples of item distribution in TCs/collection nodes/general loot roles, and provide some information and examples regarding breakthroughs. I’ll also give provide the last public information regarding game population size, to show what these numbers mean within our community. I added an example to help visualize how probabilities work using a normal 6 sided die. Hopefully this will help.
