Here is the perspective of someone who has a full team.of boosted creature and lives in the wrong side of the world: removing boosts will not make arena more fun or better. It will make arena more RNG dependent and rewards players for being in the North America continent.
Boosts themselves could be removed and replaced a better speed tie systems and some minor customisation options on dinos. So that solves the arena issue but doesn’t solve the financial problem. Even refunding every boost with 4000 HC per 100 boost points will not make players very happy since it effectively removed their creatures power by 50% so Google and Apple will have a lot of angry requests for refunds. Next part is HC sales, since those who would buy HC now do not need to given they will have easily 100s of thousands of HC, Ludia loses that revenue stream for at least a few months if not a year.
So Ludia is going to lose huge amounts of money for a year from the moment they remove boosts. Not.talking small potatoes like a few million but 10s of millions if not a 100 million from lost revenue and refunds.
