They should be replaced with 1/(1+x) mechanics. EG gs should not give -0-50% gains, but 0-100% gains reduction where 100% means the gains are mulitplied by 1/(1+1) aka 50%. Similarly for draft cost reduction, rax, TDs, ritual cost reduction, and so on.

It gets frustrating having to post this trivial improvement once a year and see it ignored, year after year. There's no reason these mechanics should be imbalanced.
