Technically a cool-down would not have "fixed" the "problem".
The stated problem is that the sets were not intended to generate new collectibles, but to allow you to auction extra collectibles. Adding a cool-down to the old sets would not allow you to sell extra collectibles.
I am assuming that they are doing this to have an excuse to not convert useless collectibles to a useful currency after the promo is over.
They are really making it hard to enjoy the game these days. I think most of us are just grinding through assuming that it will get better at some point. I am really questioning that assumption now.
