Unless you're running Titan with ruins, an Icebreaker / Hunger of Crota combo is much more versatile though.
I nearly always see people switching to Gjallahorn at the end of the mission / boss if they got an Icebreaker in their bag.
My LDR is very similar to icebreaker in stats, so i haven't found a need for icebreaker anymore outside of oracles. If Black Hammer drops for me anytime soon, I'll probably keep that around for PvE.
The name of the game changed for me with Gjallarhorn though. I just haul ass with that thing and heavy ammo isn't a problem unless we're wiping a raid repeatedly.
It's not absolutely necessary, but without it, aliens take too long to die.
