Gjallahorn doesn't need to be nerfed. It should not be sold. But, the only people who can honestly say they have "earned" it are the players that bought it the first week. They played to earn the currency it was purchased with. After that it has been up to RNG to determine who gets it. If you want to say you've earned it because of random chance then you place yourself in the same talent pool as everybody who has been last in crucible or worst player in a raid that has been granted the weapon. Skill does not determine who gets it. Play time does not factor. It is random chance that chooses. The Gjallahorn is not earned any more than the cheap velvet Elvis painting at a bingo game. I have over 1100 hours of game play with three 32 level characters, all different classes. I have yet to get a Ghorn from RNG and I've done just fine without it. Congratulations to the lucky lotto winners. But, you didn't earn it.
