I think the best solution was to raise the price of the spell books, since you yourself say that the game is not free, but the spell books are very low, changing the reward ranges of the chests will decrease the probability that A small fish can appear in the game without first investing Large amounts of money, those who can invest in Grande are applauded but those who do not have the possibility to do so will remain a small fish due to the difficulty, since previously before these such crazy changes, it was difficult to get good things in the chests, my brother spent a week opening daily rewards chests, 7 days he gave me legendary positions, now I think it will be impossible to get a card ... I hope it is the best decision although to me opinion I think they bathed the paper boat in water.
