We 've all heard that the allowed trading rates are from 3-2-1 to 2-1-1,
The way I see it, all combinations between those two ratios are legal, such as 3-1-1 or 2-2-1 and a previous admin that I asked for his opinion agreed with me.
Another admin though said to me that the metal:crystal 3:1 exchange rate is too high and the 2:2 is too low but values in between such as 3-1.9-1 or 2-1.5-1 are allowed.
Now I am quite confused and I kindly ask someone who has the authority to clarify what exactly is allowed and what are the ratio limits for every kind of exchange (metal - crystal, crystal - deuterium, metal - deuterium)
Thanks a lot!
