The Postmaster storing only 20 items is fine, but instead of first-in-first-out, legendary items and engrams shouldn't be deleted in favour of blue ones, especially in light of the fact the Heroic Strikes and possibly even Crucible encourage continued engagement for better rewards, and there's the way 3oCs stack. It's probably not a huge issue, but wouldn't it make sense to prioritise Legendary/Exotic items? I just come across this occasionally during IB and when doing Heroic Strikes (especially for the exotic faction items). One NF on my Hunter last night netted 14 items to the Postmaster. Anyone else lose any good gear to this? Such as picking up an exotic engram in the first strike in what will be a string of strikes, but it goes to PM, then after x strikes you visit tower only to find the PM full of blues and maybe a legendary but because you got the exotic early on it's been deleted?
