I really hope it’s supposed to be exponential or something close to it. GS has changed in recent patches or been bugged so it’s difficult to tell what the correct behavior is supposed to be for GS increases. The description can be read as a 100% increase over the previous amount. In that case, changing the percent increase from 100-200-300-400% to display 100-200-400-800-1600-3200% would be easier to understand the benefit.
The diety points just weren’t worth it before. Now it’s useful and necessary, otherwise the game just becomes about farming crystal to start more rituals of hatching.
The cost in diety points vs the increased GS cap for hatching currently feels perfect to me, it’s just the display % that is confusing.
