"Rethink their policy" entails the premise that this isn't their third LCG core set to be mostly 1x cards. They know what the **** they're doing, and a "Core Set Booster" pack's only reason to exist is to UNDERMINE SALES OF THE CORE SET. They never have and they never will.
The value of card variety out of the core set far exceeds the value of exceeding the $40 price point in order to either include more copies of cards or reduce the overall number of cards-by-title.
