Andy at your earlier statement that is a huge amount; of unbalance. Choose the fusion. To be equal to the lowest rate and not a median. Its just bad logic xP I can understand why you want it that way though
Meh if people are happy enough to buy level 1 legs repeatedly because it's the cheapest method, there's no use implementing something like this unless you put it to the cheapest price... Else anyone clever would just ignore it and it would become a useless feature.
