Traditionally you could get IB drops that were offered in prior weeks. My guess, we saw less drops because the only gear in the table is that being sold this week. Next IB we will have this week's and that week's. Twice the available loot. A few months down the line, we could be seeing a lot of drops. That's my hope anyway, based on what they said. They do need to drastically increase blue drops. You can get way more doing strikes. They should make them drop from guardian kills like they do pve kills. The total randomness that doesn't reward skill at the end sucks.
