I'm more than okay with it. I'm overjoyed. I received 3 Gjallarhorns from various drops, all since House of Wolves, and the weapon is a game-changer. But I have clanmates with 50 - 100% [i]more[/i] time in--people with better Grimoire than me, more raids and Nightfalls than I've ever done--that will be getting their first Gjallarhorn today, from Xur. I am amazingly happy for them; I think it's a gesture that came way too damn late. The only impact another player having Gjallarhorn can ever have on me is positive*. There is [i]literally[/i] no downside to Xur selling it. * Well, I suppose someone shooting me with it in Crucible is a potential negative impact, but there, it's just another rocket launcher anyway.
