Go get my Kin/ Defender or /Kin 'Troller, go into the sewers, and play guardian angel. SB, ID, FS & Heal sewer teams. Take a team of 2s & 3s entering the sewers (follow, not join), SB all of em, watch them charge into that first group of lvl 5 Hellions, hit Fulcrum Shift, watch the carnage... follow them, repeat...
An Empath works too.
