I find it bothersome when I have some gear that I don't need in my vault and I can't make it into armor materials & glimmer. Also I think it would be easier for those people who are unable to buy from xur when he is in the tower through the app. If I am out of town and I xur sells a (ex. galijhron) and I want be back on Destiny before xur leaves, I get so made that I couldn't by through the app and get that exotic that I have been grinding for so long and not be able to get it.
