Weeeeeell, I'm a hunter and I just tether em with shadow shot, maybe use a primary to bring their health down a bit, because if you tether the enemy, then whack them once with a sword, it is almost a oneshot. I like tethering a large group, using and auto rifle, then cleaning up with a sword, I do this in mayhem clash. 3 - 5 kills this way per super. If you get heavy you don't even need to do this.
