It has it's moments. I like it for strike bosses when a fireteam member draws its agro. Using it with the Weapons of light buff is nice. Using it with weapons of light and a weekly strike w/ solar burn damage is a feat to behold.
PS - I can also do the "Kill 2 enemies at once with fusion rifle 20 times" bounty in about 90 seconds on the "Dark Beyond" mission with a heroic modifier on. #WeveWokenTheHive!!!
