I saw people discussing this and I think they have a point. Since there would also be common and rares on other packs, the price of the commons and rares will go down a lot so buying starter packs is a sure loss of money.
On the other hand, it would be good for beginners and for renting commons and rares due to low price
I see what you're saying, and I agree that the increased supply of commons and rares from other packs will drive their prices down. That makes starter packs a bad investment if the goal is profit. However, from a gameplay perspective, cheaper commons and rares can make it easier for new players to get started and for renting to become more viable.
Do you think this would help retain more players in the long run, or would the devaluation of commons and rares hurt the ecosystem overall?
