I think the option to buy (one time purchase) some sort of starter pack would be a great addition. Increasing the cost of the spellbook and throwing in some packs though... I'm not really feeling that one. The initial cost for entry needs to remain low.
If the Spellbook is too much for new players (after an increase) they can choose to join the newer Games while their Spell-books are still cheap. This way we create scarcity by making Splinterlands an exclusive club everyone wants to join but not everyone can affort to
I feel like this kind of mentality isn't conducive to onboarding new players and/or growing the community.
