Why would a new player need to buy during the presale? The presale packs cant even be opened till the official release which is over a month from now. Also the presale is only 1 million packs of the 15 million to be sold so it isnt like new players wont be able to buy later.
Vouchers are also going to be used for other events, releases, etc etc so if you dont have many you could save them till the next thing that will take vouchers. While CL packs are $4 the next thing might be worth $30.
And the other 14 millions doesn't need vouchers? Whether we buy during the pre-sale or not doesn't make a difference. That's because unless the voucher is removed, we stake more SPS or buy vouchers we won't be able to be able to buy a single card pack.
Easy for you to say. Do you really want new players to wait for the "next thing" while older players get new powerful cards? Don't forget older players doesn't have to experience what new players are experiencing now. In the previous card pack sales they could buy card packs for cheap (and without the bullshit voucher requirement) and strengthened their decks with powerful cards. This system of requiring vouchers to buy card packs is alienating the new players of the game.
