This has been a known issue for over half a year. The earliest post that I could find specificlly about it was this one on September 2nd.
As far as I can tell, based on the devs communication and prioritization, it’s been completely ignored and will never be fixed. This is the kind of thing that makes us feel like our feedback is falling in deaf ears.
They put us in smaller pools to make the problem less apparent rather than fix it. Funnily enough, this is the same thing they did with duplicate cards by reducing the number we get at a time, rather than fixing the problem. There are mythics out there that are decisively better than others and show up in every deck once a person gets them (and this is also alongside the “problem” of top ten players getting more mythics than others), so instead of fixing that problem of balance, they just decide to give everyone less mythics.
It seems like they’d would rather not fix the problems, but shuffle things around. If they could make a little money while doing that, great.
It doesn’t help either that aside from Brigby and Alve here and Tombstone in bugs we get very little communication anyway.
