Oh thank you... I'm a f2p player so getting 2 legendary card on a free pack makes me so delighted.

I open 2 book of hero pack and it gave me 3 legendary card... 1 jaina and 1 rexxar the free pack after finishing the quest... just wondering if this is unique or every 1st card you open each hero will give you legendary card... or it will be just like normal expansion 1 legend on your very 1st 10 pack
