I am completely against this proposal. I think it is vitally important that, as cards rotate from modern, they have equal PP to Chaos Legion. Without removing the 0.5x penalty, it is conceivable that rotated modern cards will drop to valuations even LOWER than Chaos Legion since CL would always be preferred to rotated modern cards for double the PP. It would be disastrous for rotated modern cards to drop to market prices below CL and destroy their long-term value.
Not only is my vote a huge NO, I can only imagine the people who would want to vote YES for this proposal don't care about maintaining the value of modern cards.
is this going to apply to all the sets that follow is my question.
It should in my opinion. There's enough demand for modern cards with a limited supply that I think it would be safe to make all cards from Chaos Legion to the present to be worth 1x. Our new pack sales mechanic has worked well for the past few modern sets.
