No my comeback is gonna be this: I buy three of coins every week because they do work. Out of the 35 that I usually buy I'll get anywhere between 5-8 exotics which costs far less than it would be to buy them individually for 13 strange coin each and also waiting several weeks to buy them depending on when xur sells them. On top of that, you have a high chance at 310 exotics which you cannot get from xur. When we're all 310-315 we will be getting a chance at 320 exotics.
