Have you actually tried to earn strange coins? , you can't get them from a couple strikes, not enough to buy a weapon anyway, playing the weekly on level 24 only gives you 3, I run the level 30 with all three of my guardians to get my strange coins, I have gotten some of my exotics from ROC, some from bounties, and some from xur, I have over 530 hours in, a Grimore Score of 2550, but I am a noob cause I buy from Xur?. Somebody needs to come back to reality a little bit, the only "exclusive" weapons that Xur will never sell, are Raid exclusive like Vex, and bounties, like Thorn, The rest are fair game!!!
