Skirmish end of battle remaining time.
This is more an issue with the time remaining. Once you use the item to cause the weapons to drop into the loot pool, a 5min remaining timer starts. Unfortunately, items take 5min+ to drop to members, so everyone is kicked out of the zone before items leave the loot pool. This of course happens when everyone is unable to lot on items, or happens to be away from their keys. A reduced drop time or increased remaining time (6min+) will be needed to prevent entire loot pool from being lost.
Ended up loosing 6 weapons from a high tier run.
