I think it’s pretty straightforward,the grinding wont become faster or slower since you can get only 1 free container/day but being able to do that on Co-op might be more fun and easier,no matter how fast or how slow you get the 10 wins(as much as you do it in one day),its the same bad drops,so why not make them easier to get then?
But as Co-op is limited to rank 12,getting the Brokk and Karud containers will still be the same pain…
