Now I know we are all upset that Xur hasn't sold heavys for weeks. Now all we see are posts about "the heavy ammo drought of 2015". At the same time there is a group of people who claim grinding for glimmer (exclusion zone, etc) just sucks beyond belief. I agree with both sides. Just something to do however to defeat this all around is keeping 200 glimmer consumables in your vault (silken codex, house banners, etc). If you keep those in vault and then cash out only for heavys, it'll help during this non-Xur sale of heavys.
