The purpose of this is to keep prices high, when mausoleum room V (5) is unlocked, it is meant to drop some of the best gear - forcing people to run 5 maps instead of 1 for a chance at one of the best items to restrict/delay supply which is imported into an economy.
High prices - differentiation within characters - something to work for - sustain an economy?
Otherwise, people may aswell stay at outsider rank and buy all the mausoleum v (5) gear for 1k
