+1 However i doubt they could change what cash shops take as currency so just make bignotes exchangeable for ec at gods giving and take them out of the item shop.
OOOOOOOO Big notes to ec sounds super neato, make big notes purchaseable with EC and able to be reverted to EC at GG or something
Adding EC as a currency to buy things in cat shops does seem like a neat idea although I doubt it can be implemented 😥
