Even new players only purchasing the spellbook can earn thousands of reward shares (and cards) over the course of a year if I understand the math correctly. Time will tell, but I am optimistic about the rewards changes and its potential on new/veteran players alike. I think bot farms extracting value from the game will be dis-incentivized because of the 'ghost card' change. If the do still exsist, they'll probably have to merge account/resources. Maybe we see less bots?
