I've been playing since day one. I'm nowhere near a fanatic player, but I do try to play a few hours a day. I've never bought a weapon from Xur, but I have purchased armor though. With that said, I've earned several other exotic weapons, even thorn is in my arsenal. Yet the gally has always evaded me. In one day I got 3 of the same exotic weapon drop, so yeah the rng sucks at times. But I'm breaking down and buying the Gally tonight(although I will probably now have them drop like flies.) Either way, earned through randomness or purchased thru Xur, everyone has had to earn it by playing.
