I see no problem with the cost and rarity of the ingredients and materials. If you account for how much more gil is in the game now than 7 years ago, the new materials are no different than Shining Cloth/Damscene Cloth/Divine Log/Venemous Claw circa 2005. Back then those items went for 6-20mil each which was appropriate considering only a few NMs dropped these items and they were heavily camped. Level 99 abjuration gear should be rare and expensive and the HQs should be even rarer and more expensive just like at 75.
