Increased crystal costs are the same for all crafters trying to make the same crafts. One maker of marinara pizza will feel the same increase in crystal prices as every other chef on the server, so there is no advantage or disadvantage to anyone, all that needs to be done is to charge more moneys for the final product. Considering you can make money out of thin air through a variety of methods, this is hardly a real problem.

If it's too much, you could always farm crystals yourself :>
