Look I've came up with a theory of how they did this. All weapons do the same damage corresponding to its upgraded damage. So if ur a lvl 30 holding a maxed out fusion rifle against a 25 with a maxed out fusion rifle they both will Inflict the same damage. The only difference is that lvl 30 armor is stronger and will soak up More bullets then the lvl 25. But here's the tricky part with fusion rifles. Since, maxed out fusion rifles regardless of ur lvl are one shot kills, that's how the lower level killed you. He had a maxed out 77 wizard. One shot kill. U missed him too by the way
