Wasting Money: too difficult finding Rare!!!

Unknown

Hi guys,
I bought a Big Box, I spent my money, and i found only 2 Rare on 14
boosters!!!
Furthermore, here is different than Magic the card game: if you already have a card, find another one like it is completely unnecessary!!!

Review the chance of finding rare Please.
