I'm not understanding this logic. "Things are harder for a high demand service, so it will be cheaper?". Basically, enchanting will cost a lot more from what I can tell.
You want to ensorcell your 10x HCP armor, you pay out the ass for a mutant sorcerer build to do it for you. You want to enchant your 7x highly scripted item with 12 CER of weighting, plan to spend excessive amounts to get a specialized wizard to do that project. Not only will the wizard have to be specialized to complete the project, but they're going to have to successfully hunt with their specialized build or use a bunch of fixskills.
Player Enchanting should cost way more than it used to cost from this change. If people are selling it for less, they're doing it wrong.
