Negative durations builds are most commonly used in high level missions where running out of energy could mean death. As such many raid(trial) builds are focused around bringing many cc warframes focused on ccing and not killing enemies so that the ev trin can just spam ev on them. It's a purely situation build that's extremely useful assuming you have the cc to compensate for the trinity's squishyness.(Low duration > Non existant 3 > Super squishy trin)
