I have a maxed out 331 Mida but I got The Calling (legendary) last week from Nightfall. It has Firefly, Send It and a reload perk. I never knew the Firefly perk was as bad ass as it is (I always thought it was like exploding rounds which don't do much splash damage). While farming I can hit one Acolyte and the Firefly perk will take out another two. Pound for pound I'd put it up against my Mida any day.
