Aurora s prices will never be very low bcs of the demand of bonus changers, which is hugeDepending on how many people farmed changers during the Christmas event, chances are that, after the merge, Aurora's prices will be very, very low, as the supply with massively increase.
I might go as far as to say that, for 1-2 months, Aurora will feel just like Odyssey in terms of prices and ease of progression (after the merge), but who knows. It's clear, however, that the low-medium level gap will see lower prices on near-perfect equipment and such.
