Hi @PremierVenoth,
While cards between the different system need to be balanced, the overall progression is cards and credits. Adjusting one aspect (cards) means looking into the balance and potentially tuning the other (credits). And with credits being adjusted in the crate system (changing from increasing with player levels to doubling at player level 9), the bounty credits were also adjusted.
Overall, it was to ensure that the entire progression system (crates, cloning labs and bounties) were balanced and in tune with each other. Hopefully that makes sense.
