The revamp for Dynamis -INCREASED- prices on coins, byne bills are double to three times their old values, and decreased availability.
What? I can't look in a Bazaar without seeing coins these days. The Dynamis revamp made currency much more available. The only coins that seem to have raised in price are Byne bills, and the rest dropped in price by 4k so I'll ignore the 4k rise in price on them.

A Salvage revamp would do wonders for Alexandrite. Currently we have something like half a dozen Bazaars stocking Alexandrite with well over a dozen seeking to buy it, the price is certainly not going to rise if we have more Bazaars to buy from, if anything it will fall dramatically. If SE announced right now that they'd be doubling the drop rate of Alexandrite, you wouldn't go out and buy more Alexandrite for 12k, you'd at least wait to see how the update affects the pricing and the amount you can farm, and that alone should start pushing the price down before the update even goes live (for example, the price of Phalanx sky rocketed when it was announced for Paladin, think that but in reverse).
