Completed in 6 or 7 rounds. Some maps are better than others in terms of group placement of enemies. Blind watch, Twilight Gap, and Widows Court were the best. Keep TLW equipped and go to town. Get Multikills with Stormtrance and you're golden. I keep Amplitude and Transcendence on for effectiveness and longevity and Electrostatic Mind for even quicker Super charging. I'm usually first to charge up if I stay with my teammates and will usually get 4 or 5 more during the round.
