When should F2P players start saving gold for the December expansion? Mathematically speaking, when should a person stop investing into a given card pack type? I am thinking when I get to around 70% of a card pack type and 100% common cards that is a good time to stop and start saving.
Do you stop investing based on a date like bottom of the month that a set gets release? or do you stop based on percentage? And what would you recommend as a general rule?
I didn't find the right solution from the Internet.
