I like the idea of this as an option for new players, but not that you want to completely eliminate the $10 spellbook. There are players I know here in game who live in countries where $7/day is the minimum wage. I believe the success of this game comes form making it MORE accessible to as many people as possible, not LESS, and increasing costs for basics like this makes it less accessible for more people.
I really like the idea of the OPTION of buying a few packs with the spellbook but not at the cost of eliminating the $10 spellbook.
