According to bungee.net, I have played Destiny of 26 days 21 hours 8 minutes and 15 seconds since late September. No gjhallahorn yet. Even a blind squirrel finds an acorn from time to time..not me. I've done hard and normal raids, nightfall, crucible, ROC strikes, in other words everything. I think I have seen maybe 1 other player get it in a drop. Others players have said things like, "I have 4 gjhallhorns". Checking out new DLC and then might be done with this game. Tired of hunting the great white whale.
