Do beat Crota basically you always take him down with rockets which are heavy ammo guns. So when we need them most you take them away?.... They cost way to much to buy with glimmer let alone how long it takes to farm glimmer. AND THE HEAVY AMMO GLITCH WHERE YOU LOOSE IT WHEN YOU DIE DOES NOT HELP! So Xur should sell them every week because I have so many strange coins because Xur never sells anything good which is a different issue...
