If you use the mighty and holy Gjallarhorn for anything else than killing Atheon and Crota you might not be a good player. If you depend on it for a sad strike, crucible or even patrol no wonder you piss your pants at the thought that Xûr will sell it again and it might get nerfed. I have it I love it but bearly used it apart from the most challenging enemies because I'm good enough without it. Some people aren't.
