The thing I am worried about is that no one will want to spend their "hard earned" points on boosters because they could end up getting low tier cards. I think there is a very high chance that players will much rather want to spend those points on the auction to get exactly what they want, which will lead to less boosters being opened.
If opening boosters become optional I'm a bit afraid of what that will do to the card "economy". Unless a booster is included in what we get from the daily stuff.
