I like the idea of a miniset that is there purely to give value to the DOA and SPS holders. It gives a reason to buy/use SPS and locks it up in the short run with an option for the DOA to use it later down the line if needed. It remains an eternal conflict between Company revenue and player earnings. The entire DEC to Peg narrative the way I see it is mostly there for the company to earn and not having to cut back on the too high expenses.
SPS is the reward currency and there needs to be valid reasons for player to buy it which would be less the case if Riftwatchers was sold in DEC. I agree that we don't need another Mini-Set and the requirement should be Riftwatchers to sell out before a new once can come. Card inflation is just way off the chart. New game modes, better new player experience is where the focus should be on. In the end, more new investors is the only real way to make things recover.
