I bought 3 this weekend! Greatest feeling ever to finally have every exotic. Gjallarhorn has never dropped for me and I don't think it ever will. I've carried noobs through nightfalls and they've gotten it, I've seen many people get it out of atheon chest and deathsinger. I've had the person that was dead the whole crota on hard encounter get the damn gun! This gun seems to mock me in every way rngesuslly possible but finally I have it and can say FK YOU GJALLAHORN!
