If you have been playing Destiny for a good part of this 30 years, then Gjallarhorn was already earned and was a good weapon until nerfed into oblivion. It's too bad that we have to go through a quest all over again. The dungeon is pure misery, and probably to only get a weapon that is way below expectations. Interesting in 30 years of Destiny how the enemies get stronger and the Guardians equipment gets weaker, maybe that is the 30 year "destiny".
