Greetings!
Starting with the next round of Deadpool’s Daily Quest (July 12, 2016) updates will be made to the contents of the DDQ Vault in order to increase the Iso-8 on offer. Here are details and a chart from Demiurge:
"We updated the contents in the vault to provide players with more opportunities to get Iso-8 rewards. We have added an additional 27,500 Iso-8 to the vault (a total of 92,500 Iso-8). We also increased the percentage to get an Iso-8 reward to 32% (from 11%).
To account for these changes, we removed 21 5-Health packs (but added 3 10-Health Packs) and 46 random 2-Star character rewards. Please see the below table for the contents of the new Deadpool Daily Vault."
